Would it be possible to add a menu (comparable to the search for duplicates) or an advanced search at the group level to have a list of groups without specified managers? with the option to choose to filter on read-only groups activated or not activated (group option).

This request came from the observation of an unidentified group modification over several months (long live the paper version which continues) with an entire service that no longer had access to its groups. It's blocking major changes (e.g. preparing for next year).

If it already exists, I would like to know how to do it ^^
