Which scope is required to download a feedback document from an assignment?

I am trying to download feedback documents from assignments (dropbox) using this API call:
GET /d2l/api/le/(version)/(orgUnitId)/dropbox/folders/(folderId)/feedback/(entityType)/(entityId)/attachments/(fileId)
It gives met a 403 (Not Authorized) error. The user running the API call is a Super Admin and in Brightspace it is allowed to open the feedback file so I think it's a scope issue but the scope for this end point is not documented at: https://docs.valence.desire2learn.com/http-scopestable.html#
Does anybody know which scope I have to use?
Downloading the students submissions files via /d2l/api/le/(version)/(orgUnitId)/dropbox/folders/(folderId)/submissions/(submissionId)/files/(fileId) works fine

I found the cause of my problem. I forgot to include the Bearer token in the request. Including that one helps :)
