/v2/attendance token scope invalid

Hi!

I've been trying to generate a valid access token to use the List attendance periods endpoint.

This is my request

curl --request GET \
     --url https://api.personio.de/v2/attendance-periods \
     --header 'accept: application/json' \
     --header 'authorization: Bearer TOKEN'

This is the response I get

{
  "personio_trace_id": "f9eddcad-e93c-4d7f-a6b3-76caf2eec677",
  "timestamp": "2024-09-18T09:37:58Z",
  "errors": [
    {
      "title": "Insufficient access scope",
      "detail": "Client scope insufficient to access resource",
      "type": "https://developer.personio.de/v2.0/page/public-api-error-codes#commonforbidden",
      "_meta": {}
    }
  ]
}

Unfortunately there is no documentation on which scope I exactly need to access this resource, my token has the "attendances:read" scope, but this doesn't seem to be the correct one. I've also tried "personio:attendances:read", but that seems to be an invalid scope (I just guessed that one, since there's no documentation on it).

Would be a pleasure if you could give me a hint on how to obtain a valid token to work with the v2 attendances API!

All the best
