As per my github doc request. https://github.com/microsoftgraph/microsoft-graph-docs/issues/11881
I see that https://graph.microsoft.com/v1.0/groups/{id}/transitiveMembers/microsoft.graph.user returns users but
https://graph.microsoft.com/v1.0/groups/{id}/transitiveMembers/microsoft.graph.group does not return group, it just returns a bad request. This is inconsitient with the /groups/{id}/members endpoint.
In this case I am only trying to return transitiveMembers that are groups, but i cannot find a filter that works. The github reviewer has re produced this and marked it as a bug.
Where do I submit this as it is a legitimate issue that was holding a project i was on ?
