rooms.listWithReadStatus returns 400 without explanation

[brettdh]

Describe the bug
When using a personal access token, rooms.listWithReadStatus returns a 400 error, with no explanation why. It turns out that using an OAuth integration allows this call to work fine, and the reason why doesn't appear to be documented. Any SDK differences for different auth methods should be documented, and the error returned should be more helpful.

To Reproduce
Steps to reproduce the behavior:

1. Initalize the SDK with a personal access token
2. Call webex.rooms.listWithReadStatus()
3. Observe 400 error with no error message

Expected behavior

• Error messages should contain an explanation of what happened
• SDK documentation should describe whatever limitations exist when using a personal access token
