List required permissions when invalid permissions error occurs?

[jeking3]

Description of the new feature

It would be really helpful if the set of required permissions, or the specific permission that caused the failure, was part of the response. Given permissions required per API are undocumented, figuring out what permission caused an error is incredibly challenging.

Relates to #6843, #9266, #9272

Proposed implementation details (optional)

@jeking3, thanks for opening this issue, we are working to find the best way to document the required permissions per API.
