We are using friend system of playfab, and i'm trying to make that player "Tony", could apply for his friend "Timmy" group. I found out, that ListMembership, could retrieve the groups of a player, which sounds perfect for this task.
But after some testing, i just found that the request, only retrieves data if the user is already inside of the group. So "Tony" cant get the IdGroup, to send an application for it.
Could it be the policy? It does not return any error
