I’m currently restricting the regular members list to active MemberPress members by doing this:

add_filter('bp_after_has_members_parse_args', 'mikes_member_list' );

Where ‘mikes_member_list’ is a function that gets the IDs of members who are inactive and then excludes them from the returned args.

Is there a similar way to modify the list of members in a group?

Thanks!
