I know that group owners can manage group membership from https://account.activedirectory.windowsazure.com/r#/groups. However, we don't want to enable that interface as it allows any user to request membership to groups. We'd also like to avoid having them use portal.azure.com, as it's a bit much for non-technical users to navigate. Is there some simple UI that would just allow them to add and remove members from a security group?
