401 Unauthorized on CXone v2 Reporting API for real-time queue stats

Having some config trouble here… 401 Unauthorized. access_denied.

  1. I generate a token using client_credentials grant.
  2. I hit GET https://api.cxone.com/v2/reporting/queues/realtime.
  3. I get 401.

The token works for /users/me. Why does the reporting endpoint fail? I am using Python requests library. The scope is reporting:query. Is there a specific scope for realtime?
