Database collection only readable by admin Function

Hi there !

I'm trying to access a specific Document in a specific Collection within a Function.
But the Function keeps crashing telling me the Document with the requested ID could not be found

I'm sure the document exist and the collection ID (and DB ID) are good.

The thing is, there is no permission on the Collection as I want this collection to be only accessible with the admin rights of the Funciton (no user can access it).

Here is the code I used

const adminClient = new Client()
        .setEndpoint(Bun.env['APPWRITE_FUNCTION_API_ENDPOINT'] as string)
        .setProject(Bun.env['APPWRITE_FUNCTION_PROJECT_ID'] as string)
        .setKey(Bun.env['x-appwrite-key'] as string);

const adminDatabase = new Databases(adminClient);

const prompt = await adminDatabase.getDocument(
        DB, 
        PROMPTS, 
        documentID, 
        [Query.select(['content'])]
);

Again, I am sure that documentID exists in PROMPTS...

Is there a specific permission to add in this case ? I'm a bit lost in this.
