Extract List of Observees from Canvas Data

[charles_lim1]

Canvas API have 

GET /api/v1/users/:user_id/observees

GET /api/v1/users/:user_id/observers

How do I get these information from Canvas Data Files? Canvas Data have the enrollment_dim.txt, which has the type = ObserverEnrollment. I believe that is to say the user_id is an observer. But it does not say which students the person is observing.

I would like to know this, too. Is this information available in Canvas Data at all? I get the impression it isn't...
