Facebook recently added the "Allow Pages to request to join as group members" setting in group settings, but I can't find how to make my page request to join as a group member. I have tried on groups where I am an admin as as well as groups that I am not. When I click "Join Group", Facebook does not ask me if I want to join the group as my personal profile or as my page. Please note that my question is NOT about linking a page to a group (that requires being an admin of both), it is about becoming a member of group as a page. Is this an unfinished feature or am I missing something?
