It seems like the API documentation is missing some crucial information. I'm trying to integrate group admin controls in my app (e.g. changing members' roles), but the documentation doesn't include the endpoint to accomplish this. I've managed to dig some up by observing network requests via Chrome's developer tools, but I've having trouble with others (e.g. determining the authenticated user's role/ privileges in a given group). Ideally the group member's role would be returned as a part of "Get User's Groups", but it would be sufficient to fetch this info on a group-by-group basis if that's currently possible.
