It used to be possible to add a group of users to roles (Administrators/Developers/Testers) - we have some apps with this still set up. See this obselete Facebook blog post from 2011 detailing this functionality.
However, the add group functionality seems to have been removed - add there's no add group option any more, just "Type in a name or ID of the user you want to add".
Am I right in thinking it's now impossible to make add a group to a role of a Facebook app?
