anonymous_id missing in Course-Assignment Submission endpoint

[ido-nl]

Hi,

I am using this endpoint 

GET /api/v1/courses/:course_id/assignments/:assignment_id/submissions

I have 2 users, both have the Teacher role in the course ("role": "TeacherEnrollment")

For user 1 it does show the anonymous_id (when using its API token), but for user 2 it doesn't (when using the API token from user 2), when getting the submissions.

Strange uh!

It is so that user 2 was originally entered as a student, but I change the role to Teacher, you would expect both users would behave the same.

When using the API to get the Course Enrollments or Course users. both users seem to have the same values.

1. How come both users produce different output?
2. Is there a way for me to see the difference between the 2 users?

I do not understand 

[ido-nl]

I think I found the reason, didnt notice this line before in the API documentation

anonymous_id
A unique short ID identifying this submission without reference to the owning user. Only included if the caller has administrator access for the current account.

I guess my user has admin access and the others dont.
