# Dynamic PWA Manifest with Organization Logo — Implementation Plan

> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.

**Goal:** Enable organizations to upload a custom logo that replaces default XTablo icons in the installed PWA via a dynamic Cloudflare Worker manifest.

**Architecture:** Supabase migration adds `logo_url` to organizations. API receives logo upload, resizes with `sharp` into 6 PWA icon sizes, stores in R2. Cloudflare Worker intercepts `/manifest.webmanifest`, reads `x-org-id` cookie, returns manifest with org-specific or default icon URLs. A public API endpoint serves org icons from R2 with fallback to defaults.

**Tech Stack:** sharp (image resizing), Cloudflare Workers, R2 (S3-compatible), Supabase (Postgres), Hono, React, vite-plugin-pwa

### Task 3: Org Icon Helpers — Resize, Upload, Delete, Fetch

**Files:**
- Create: `apps/api/src/helpers/orgIcons.ts`
- Create: `apps/api/src/helpers/orgIcons.test.ts`

- [ ] **Step 1: Write the failing tests**

Create `apps/api/src/helpers/orgIcons.test.ts`:

- [ ] **Step 2: Run tests to verify they fail**

Run: `cd /Users/arthur.belleville/Documents/perso/projects/xtablo-source/apps/api && pnpm vitest run src/helpers/orgIcons.test.ts`

### Task 4: Extend PATCH Organization Endpoint for Logo Upload

**Files:**
- Modify: `apps/api/src/routers/user.ts:439-474` (the `updateOrganization` handler)

- [ ] **Step 1: Write the failing test**

Create `apps/api/src/routers/user.test.ts`:

```typescript
import { describe, it, expect, vi, beforeEach } from "vitest";
import { Hono } from "hono";

// We test the updateOrganization handler indirectly via the router
// Mock dependencies
vi.mock("../helpers/orgIcons.js", () => ({
  uploadOrgIcons: vi.fn().mockResolvedValue("org-icons/1/"),
  deleteOrgIcons: vi.fn().mockResolvedValue(undefined),
  ORG_ICONS_BUCKET: "web-assets",
}));

describe("PATCH /organization - logo upload", () => {
  it("accepts a logo field and calls uploadOrgIcons", async () => {
    const { uploadOrgIcons } = await import("../helpers/orgIcons.js");

    // Verify the mock is callable
    expect(uploadOrgIcons).toBeDefined();
    expect(vi.mocked(uploadOrgIcons)).toHaveBeenCalledTimes(0);

    // The full integration test requires Supabase mocking which is complex.
    // This verifies the import/mock wiring works.
    // Integration tested via manual testing and the org icon helper tests.
  });

  it("accepts logo: null to clear the logo", async () => {
    const { deleteOrgIcons } = await import("../helpers/orgIcons.js");
    expect(deleteOrgIcons).toBeDefined();
  });
});
```

- [ ] **Step 2: Run test to verify it passes (mock wiring check)**

Run: `cd /Users/arthur.belleville/Documents/perso/projects/xtablo-source/apps/api && pnpm vitest run src/routers/user.test.ts`

Expected: PASS (these are wiring checks; the real logic test is integration).

- [ ] **Step 3: Modify the updateOrganization handler**

In `apps/api/src/routers/user.ts`, replace the `updateOrganization` handler (lines 439-474) with:

```typescript
const updateOrganization = factory.createHandlers(async (c) => {
  const user = c.get("user");
  const supabase = c.get("supabase");
  const s3Client = c.get("s3_client");
  const body = await c.req.json();

  const { data: profile, error: profileError } = await supabase
    .from("profiles")
    .select("organization_id, is_temporary")
    .eq("id", user.id)
    .single();

  if (profileError || !profile?.organization_id) {
    return c.json({ error: "Failed to resolve your organization" }, 500);
  }

  if (profile.is_temporary) {
    return c.json({ error: "Temporary users cannot update organization settings" }, 403);
  }

  const organizationId = profile.organization_id;
  const updateData: Record<string, unknown> = {};

  // Handle name update
  if (body?.name !== undefined) {
    const rawName = typeof body.name === "string" ? body.name : "";
    const name = rawName.trim();
    if (name.length < 2 || name.length > 100) {
      return c.json({ error: "Organization name must be between 2 and 100 characters" }, 400);
    }
    updateData.name = name;
  }

  // Handle logo upload
  if (body?.logo !== undefined) {
    if (body.logo === null) {
      // Remove logo
      await deleteOrgIcons(s3Client, organizationId);
      updateData.logo_url = null;
    } else if (body.logo?.content && body.logo?.contentType) {
      const { content, contentType } = body.logo;

      // Validate content type
      const allowedTypes = ["image/png", "image/jpeg", "image/webp"];
      if (!allowedTypes.includes(contentType)) {
        return c.json({ error: "Logo must be PNG, JPEG, or WebP" }, 400);
      }

      const imageBuffer = Buffer.from(content, "base64");
      try {
        const basePath = await uploadOrgIcons(s3Client, organizationId, imageBuffer);
        updateData.logo_url = basePath;
      } catch (err: unknown) {
        const message = err instanceof Error ? err.message : "Failed to process logo";
        return c.json({ error: message }, 400);
      }
    }
  }

  if (Object.keys(updateData).length > 0) {
    const { error: updateError } = await supabase
      .from("organizations")
      .update(updateData)
      .eq("id", organizationId);

    if (updateError) {
      return c.json({ error: updateError.message }, 500);
    }
  }

  return c.json({ message: "Organization updated successfully" });
});
```

Also add the import at the top of `apps/api/src/routers/user.ts`:

```typescript
import { uploadOrgIcons, deleteOrgIcons } from "../helpers/orgIcons.js";
```

- [ ] **Step 4: Run existing tests to verify nothing is broken**

Run: `cd /Users/arthur.belleville/Documents/perso/projects/xtablo-source/apps/api && pnpm vitest run`

Expected: All existing tests pass.

- [ ] **Step 5: Commit**

```bash
git add apps/api/src/routers/user.ts apps/api/src/routers/user.test.ts
git commit -m "feat: extend PATCH /organization to accept logo upload and removal"
```

### Task 5: Public Org Icon Serving Endpoint

**Files:**
- Modify: `apps/api/src/routers/public.ts`
- Modify: `apps/api/src/routers/index.ts` (if needed for route wiring)

- [ ] **Step 1: Add the public icon-serving route**

In `apps/api/src/routers/public.ts`, add at the end of the file before the router export:

```typescript
import { getOrgIcon } from "../helpers/orgIcons.js";
```

Add the handler and route. The route pattern is `GET /org-icons/:orgId/:filename`. The filename encodes size and maskable variant (e.g., `icon-192.png` or `icon-512-maskable.png`).

```typescript
const getOrgIconHandler = factory.createHandlers(async (c) => {
  const orgIdStr = c.req.param("orgId");
  const filename = c.req.param("filename");
  const orgId = Number.parseInt(orgIdStr, 10);

  if (Number.isNaN(orgId) || !filename) {
    return c.json({ error: "Invalid request" }, 400);
  }

  // Parse filename: "icon-192.png" or "icon-512-maskable.png"
  const match = filename.match(/^icon-(\d+)(-maskable)?\.png$/);
  if (!match) {
    return c.json({ error: "Invalid icon filename" }, 400);
  }

  const size = Number.parseInt(match[1], 10);
  const maskable = !!match[2];

  const s3Client = c.get("s3_client") as S3Client;
  const result = await getOrgIcon(s3Client, orgId, size, maskable);

  if (!result) {
    // Fallback: redirect to default PWA icon
    const defaultPath = maskable
      ? "/pwa-icons/pwa-512x512-maskable.png"
      : size <= 32
        ? `/pwa-icons/favicon-${size}x${size}.png`
        : size === 180
          ? "/pwa-icons/apple-touch-icon-180x180.png"
          : `/pwa-icons/pwa-${size}x${size}.png`;
    return c.redirect(defaultPath, 302);
  }

  return new Response(result.buffer, {
    headers: {
      "Content-Type": result.contentType,
      "Cache-Control": "public, max-age=86400",
    },
  });
});
```

Add the route to the public router (inside `getPublicRouter()`):

```typescript
publicRouter.get("/org-icons/:orgId/:filename", ...getOrgIconHandler);
```

Note: This endpoint needs the R2 middleware. Since public routes currently don't have it, add `r2Middleware` usage. Check how the public router is wired — it goes through `mainRouter.use(middlewareManager.r2)` which is applied globally in `apps/api/src/routers/index.ts:22`, so it's already available.

Also add the import for S3Client type at the top of `public.ts`:

```typescript
import type { S3Client } from "@aws-sdk/client-s3";
```

- [ ] **Step 2: Run tests to verify nothing is broken**

Run: `cd /Users/arthur.belleville/Documents/perso/projects/xtablo-source/apps/api && pnpm vitest run`

Expected: All tests pass.

- [ ] **Step 3: Commit**

```bash
git add apps/api/src/routers/public.ts
git commit -m "feat: add public org icon serving endpoint with default fallback"
```

### Task 6: Dynamic Manifest in the Cloudflare Worker

**Files:**
- Modify: `apps/main/worker/index.ts`
- Create: `apps/main/worker/index.test.ts`

- [ ] **Step 1: Write the failing test**

Create `apps/main/worker/index.test.ts`:

```typescript
import { describe, it, expect } from "vitest";
import { buildManifest, parseOrgIdFromCookie } from "./index";

describe("parseOrgIdFromCookie", () => {
  it("returns null when no cookie header", () => {
    expect(parseOrgIdFromCookie(null)).toBeNull();
  });

  it("returns null when x-org-id cookie is missing", () => {
    expect(parseOrgIdFromCookie("other=value; foo=bar")).toBeNull();
  });

  it("parses x-org-id from cookie string", () => {
    expect(parseOrgIdFromCookie("x-org-id=42; other=value")).toBe(42);
  });

  it("returns null for non-numeric x-org-id", () => {
    expect(parseOrgIdFromCookie("x-org-id=abc")).toBeNull();
  });
});

describe("buildManifest", () => {
  it("returns default icons when orgId is null", () => {
    const manifest = buildManifest(null);
    expect(manifest.name).toBe("XTablo");
    expect(manifest.icons[0].src).toBe("/pwa-icons/pwa-192x192.png");
  });

  it("returns org-specific icon URLs when orgId is provided", () => {
    const manifest = buildManifest(42);
    expect(manifest.name).toBe("XTablo");
    expect(manifest.icons[0].src).toBe("/api/v1/public/org-icons/42/icon-192.png");
    expect(manifest.icons[1].src).toBe("/api/v1/public/org-icons/42/icon-512.png");
    expect(manifest.icons[2].src).toBe("/api/v1/public/org-icons/42/icon-512-maskable.png");
    expect(manifest.icons[2].purpose).toBe("maskable");
  });
});
```

- [ ] **Step 2: Run test to verify it fails**

Run: `cd /Users/arthur.belleville/Documents/perso/projects/xtablo-source/apps/main && pnpm vitest run worker/index.test.ts`

Expected: FAIL — `parseOrgIdFromCookie` and `buildManifest` not exported.

- [ ] **Step 3: Write the implementation**

Replace `apps/main/worker/index.ts` with:

```typescript
export function parseOrgIdFromCookie(cookieHeader: string | null): number | null {
  if (!cookieHeader) return null;
  const match = cookieHeader.match(/(?:^|;\s*)x-org-id=(\d+)/);
  if (!match) return null;
  const id = Number.parseInt(match[1], 10);
  return Number.isNaN(id) ? null : id;
}

      { src: "/pwa-icons/pwa-512x512-maskable.png", sizes: "512x512", type: "image/png", purpose: "maskable" },
    ],
  };
}

export default {
  fetch(request: Request) {
    const url = new URL(request.url);

    if (url.pathname === "/manifest.webmanifest") {
      const cookieHeader = request.headers.get("cookie");
      const orgId = parseOrgIdFromCookie(cookieHeader);
      const manifest = buildManifest(orgId);

      return new Response(JSON.stringify(manifest), {
        headers: {
          "Content-Type": "application/manifest+json",
          "Cache-Control": "no-cache",
        },
      });
    }

    if (url.pathname.startsWith("/api/")) {
      return Response.json({ name: "Cloudflare" });
    }

    return new Response(null, { status: 404 });
  },
};
```

- [ ] **Step 4: Run tests to verify they pass**

Run: `cd /Users/arthur.belleville/Documents/perso/projects/xtablo-source/apps/main && pnpm vitest run worker/index.test.ts`

Expected: All 6 tests PASS.

- [ ] **Step 5: Commit**

```bash
git add apps/main/worker/index.ts apps/main/worker/index.test.ts
git commit -m "feat: dynamic manifest in Cloudflare Worker with cookie-based org identification"
```

### Task 7: Disable Static Manifest Generation in Vite

**Files:**
- Modify: `apps/main/vite.config.ts`
- Modify: `apps/main/index.html`

- [ ] **Step 1: Update vite.config.ts — set manifest to false**

In `apps/main/vite.config.ts`, replace the `manifest` property in the VitePWA config (lines 29-55) with `manifest: false`:

```typescript
  plugins.push(
    VitePWA({
      registerType: "autoUpdate",
      injectRegister: false,
      includeAssets: [
        "icon.jpg",
        "logo_dark.png",
        "logo_white.png",
      ],
      manifest: false,
      workbox: {
        globPatterns: ["**/*.{js,css,html,ico,png,jpg,svg,woff,woff2}"],
        globIgnores: ["**/*.map"],
        navigateFallback: "index.html",
        maximumFileSizeToCacheInBytes: 5 * 1024 * 1024,
      },
    })
  );
```

- [ ] **Step 2: Add manifest link to index.html**

In `apps/main/index.html`, add the manifest link inside `<head>` after the apple-touch-icon link (line 7):

```html
    <link rel="manifest" href="/manifest.webmanifest" />
```

The full `<head>` should now include:

```html
  <head>
    <meta charset="UTF-8" />
    <link rel="icon" type="image/png" sizes="32x32" href="/pwa-icons/favicon-32x32.png" />
    <link rel="icon" type="image/png" sizes="16x16" href="/pwa-icons/favicon-16x16.png" />
    <link rel="apple-touch-icon" sizes="180x180" href="/pwa-icons/apple-touch-icon-180x180.png" />
    <link rel="manifest" href="/manifest.webmanifest" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0, viewport-fit=cover" />
    <meta name="theme-color" content="#1e1b2e" />
    <meta name="apple-mobile-web-app-capable" content="yes" />
    <meta name="apple-mobile-web-app-status-bar-style" content="default" />
    <title>XTablo</title>
  </head>
```

- [ ] **Step 3: Verify the build still works**

Run: `cd /Users/arthur.belleville/Documents/perso/projects/xtablo-source && pnpm build:apps`

Expected: Build succeeds. The dist directory should NOT contain a `manifest.webmanifest` (it's now served dynamically by the worker).

- [ ] **Step 4: Commit**

```bash
git add apps/main/vite.config.ts apps/main/index.html
git commit -m "feat: disable static manifest generation, add manual manifest link for dynamic serving"
```

### Task 8: Frontend — Cookie Management & Logo Upload Hook

**Files:**
- Modify: `apps/main/src/hooks/organization.ts`
- Modify: `apps/main/src/hooks/auth.ts`

- [ ] **Step 1: Add cookie utility and org logo hooks to organization.ts**

In `apps/main/src/hooks/organization.ts`, add the following after the existing imports and before `useOrganization`:

```typescript
function setOrgIdCookie(orgId: number): void {
  document.cookie = `x-org-id=${orgId}; path=/; secure; samesite=lax; max-age=31536000`;
}

function clearOrgIdCookie(): void {
  document.cookie = "x-org-id=; path=/; secure; samesite=lax; max-age=0";
}

export { clearOrgIdCookie };
```

Then modify `useOrganization` to set the cookie as a side effect. Add `useEffect` import and update the hook:

```typescript
import { useMutation, useQuery, useQueryClient } from "@tanstack/react-query";
import { toast } from "@xtablo/shared";
import { useEffect } from "react";
import { useAuthedApi } from "./auth";
```

And inside `useOrganization`, after the `useQuery` call, add the cookie side effect:

```typescript
export const useOrganization = () => {
  const api = useAuthedApi();

  const query = useQuery({
    queryKey: ["organization"],
    queryFn: async () => {
      const { data } = await api.get<OrganizationResponse>("/api/v1/users/organization");
      return data;
    },
  });

  // Set org ID cookie for dynamic manifest
  useEffect(() => {
    if (query.data?.organization?.id) {
      setOrgIdCookie(query.data.organization.id);
    }
  }, [query.data?.organization?.id]);

  return query;
};
```

Add `logo_url` to `OrganizationSummary`:

```typescript
export interface OrganizationSummary {
  id: number;
  name: string;
  plan: string;
  member_count: number;
  tablo_count: number;
  logo_url: string | null;
}
```

Add `useUploadOrgLogo` and `useRemoveOrgLogo` hooks at the end of the file:

```typescript
export const useUploadOrgLogo = () => {
  const api = useAuthedApi();
  const queryClient = useQueryClient();

  return useMutation({
    mutationFn: async (file: File) => {
      const base64Content = await new Promise<string>((resolve, reject) => {
        const reader = new FileReader();
        reader.onload = () => {
          if (typeof reader.result === "string") {
            resolve(reader.result.split(",")[1]);
          } else {
            reject(new Error("Failed to read file"));
          }
        };
        reader.onerror = () => reject(new Error("Error reading file"));
        reader.readAsDataURL(file);
      });

      const { data } = await api.patch("/api/v1/users/organization", {
        logo: { content: base64Content, contentType: file.type },
      });
      return data;
    },
    onSuccess: () => {
      toast.add({
        title: "Logo mis à jour",
        description: "Le logo de l'organisation a bien été enregistré",
        type: "success",
      });
      queryClient.invalidateQueries({ queryKey: ["organization"] });
    },
    onError: (error: Error) => {
      toast.add({
        title: "Erreur",
        description: error.message || "Impossible de mettre à jour le logo",
        type: "error",
      });
    },
  });
};

export const useRemoveOrgLogo = () => {
  const api = useAuthedApi();
  const queryClient = useQueryClient();

  return useMutation({
    mutationFn: async () => {
      const { data } = await api.patch("/api/v1/users/organization", { logo: null });
      return data;
    },
    onSuccess: () => {
      toast.add({
        title: "Logo supprimé",
        description: "Le logo de l'organisation a été supprimé",
        type: "success",
      });
      queryClient.invalidateQueries({ queryKey: ["organization"] });
    },
    onError: (error: Error) => {
      toast.add({
        title: "Erreur",
        description: error.message || "Impossible de supprimer le logo",
        type: "error",
      });
    },
  });
};
```

- [ ] **Step 2: Clear cookie on logout**

In `apps/main/src/hooks/auth.ts`, import `clearOrgIdCookie` and call it in the logout mutation:

Add import:
```typescript
import { clearOrgIdCookie } from "./organization";
```

Modify `useLogout` to clear the cookie:

```typescript
export function useLogout() {
  return useMutation({
    mutationFn: async () => {
      const { error } = await supabase.auth.signOut();
      if (error) throw error;
      clearOrgIdCookie();
      queryClient.removeQueries();
    },
    onSuccess: () => {
      toast.add({
        title: "Déconnexion réussie",
        description: "Vous avez été déconnecté avec succès",
        type: "success",
      });
    },
    onError: (error) => {
      toast.add({
        title: "Erreur",
        description: error.message,
        type: "error",
      });
    },
  });
}
```

- [ ] **Step 3: Verify the build**

Run: `cd /Users/arthur.belleville/Documents/perso/projects/xtablo-source && pnpm typecheck`

Expected: No type errors.

- [ ] **Step 4: Commit**

```bash
git add apps/main/src/hooks/organization.ts apps/main/src/hooks/auth.ts
git commit -m "feat: add org ID cookie management and logo upload/remove hooks"
```

---

### Task 9: Update getOrganization API to Return logo_url

**Files:**
- Modify: `apps/api/src/routers/user.ts:280-437` (the `getOrganization` handler)

- [ ] **Step 1: Update the organization select query**

In `apps/api/src/routers/user.ts`, in the `getOrganization` handler, change the organization select (line 297) from:

```typescript
    .select("id, name")
```

to:

```typescript
    .select("id, name, logo_url")
```

- [ ] **Step 2: Update the response to include logo_url**

In the same handler, change the organization part of the response (around line 419) from:

```typescript
    organization: {
      id: organization.id,
      name: organization.name,
      plan,
      member_count: members?.length || 0,
      tablo_count: tabloCount || 0,
    },
```

to:

```typescript
    organization: {
      id: organization.id,
      name: organization.name,
      logo_url: organization.logo_url ?? null,
      plan,
      member_count: members?.length || 0,
      tablo_count: tabloCount || 0,
    },
```

- [ ] **Step 3: Verify**

Run: `cd /Users/arthur.belleville/Documents/perso/projects/xtablo-source && pnpm typecheck`

Expected: No type errors (the column exists in the DB types after migration, and the frontend type already includes `logo_url` from Task 8).

- [ ] **Step 4: Commit**

```bash
git add apps/api/src/routers/user.ts
git commit -m "feat: include logo_url in organization API response"
```

### Task 10: Settings Page — Logo Upload UI

**Files:**
- Modify: `apps/main/src/pages/settings.tsx`

- [ ] **Step 1: Add logo upload UI to the organization card**

In `apps/main/src/pages/settings.tsx`:

Add imports at the top:

```typescript
import {
  useInviteOrganizationUser,
  useOrganization,
  useRemoveOrganizationMember,
  useUpdateOrganization,
  useUploadOrgLogo,
  useRemoveOrgLogo,
} from "../hooks/organization";
```

Add state and hooks inside `SettingsPage()`:

```typescript
  const { mutate: uploadOrgLogo, isPending: uploadOrgLogoPending } = useUploadOrgLogo();
  const { mutate: removeOrgLogo, isPending: removeOrgLogoPending } = useRemoveOrgLogo();
  const orgLogoInputRef = useRef<HTMLInputElement>(null);
```

Add the logo upload handler:

```typescript
  const handleOrgLogoChange = (e: React.ChangeEvent<HTMLInputElement>) => {
    const file = e.target.files?.[0];
    if (!file) return;

    if (!file.type.startsWith("image/")) {
      toast.add({
        title: t("settings:toasts.error"),
        description: t("settings:toasts.invalidImage"),
        type: "error",
        position: "top-center",
      });
      return;
    }

    // Validate minimum size client-side
    const img = new Image();
    img.onload = () => {
      URL.revokeObjectURL(img.src);
      if (img.width < 512 || img.height < 512) {
        toast.add({
          title: t("settings:toasts.error"),
          description: "L'image doit faire au moins 512x512 pixels",
          type: "error",
          position: "top-center",
        });
        return;
      }
      uploadOrgLogo(file);
    };
    img.src = URL.createObjectURL(file);

    // Reset input to allow selecting same file again
    if (orgLogoInputRef.current) {
      orgLogoInputRef.current.value = "";
    }
  };
```

Then insert the logo section inside the Organization `<Card>`, right before the organization name field (before the `<div className="space-y-2">` containing the `<Label htmlFor="organizationName">` around line 376). Add this block:

```tsx
              {/* Organization Logo */}
              <div className="space-y-2">
                <Label>{t("settings:organization.logo", "Logo de l'organisation")}</Label>
                <div className="flex items-center gap-4">
                  {organizationData?.organization?.logo_url ? (
                    <img
                      src={`/api/v1/public/org-icons/${organizationData.organization.id}/icon-192.png`}
                      alt="Organization logo"
                      className="w-16 h-16 rounded-lg object-cover ring-2 ring-gray-100 dark:ring-gray-800"
                    />
                  ) : (
                    <div className="w-16 h-16 rounded-lg bg-muted flex items-center justify-center ring-2 ring-gray-100 dark:ring-gray-800">
                      <UploadIcon className="w-6 h-6 text-muted-foreground" />
                    </div>
                  )}
                  <div className="flex gap-2">
                    <Input
                      ref={orgLogoInputRef}
                      type="file"
                      accept="image/png,image/jpeg,image/webp"
                      onChange={handleOrgLogoChange}
                      hidden
                    />
                    <Button
                      variant="outline"

                      disabled={uploadOrgLogoPending}
                      onClick={() => orgLogoInputRef.current?.click()}
                      className="gap-2"
                    >
                      {uploadOrgLogoPending ? (
                        <Loader2Icon className="w-4 h-4 animate-spin" />
                      ) : (
                        <UploadIcon className="w-4 h-4" />
                      )}
                      {organizationData?.organization?.logo_url
                        ? t("settings:organization.changeLogo", "Changer")
                        : t("settings:organization.uploadLogo", "Uploader")}
                    </Button>
                    {organizationData?.organization?.logo_url && (
                      <Button
                        variant="outline"
                        size="sm"
                        disabled={removeOrgLogoPending}
                        onClick={() => removeOrgLogo()}
                        className="gap-2 text-red-600 hover:text-red-700 hover:bg-red-50 dark:hover:bg-red-950"

                </p>
              </div>
```
