I receive the error when trying to add a group to a collaboration :

403 - “The request requires higher privileges than provided by the access token”.

But when I try to add a user, using the user's email, it works fine with the same token.

Note: I’m using a Client/User Authentication App, and although the app does not have the “manage_groups” scope, it has “root_readwrite” (which, according to the docs, should be enough to create collaborations).

Am I missing something?

Request body:

{
       "item": {
         "type": "file",
         "id": "xxxx"
       },
       "accessible_by": {
         "type": "group",
         "id": "xxxxx"
       },
       "role": "viewer"
     }

Thank you.
