Hello, does someone know off hand the way to get the information about if a user that is going to post a message is in a group with limited visibility, and to get the guid of the users that can see this post ? I have been having trouble because the access_id is apparently 1 no matter the group where i post-

Also, i have friends collections, and can retrieve the id of the collection using the access_id of the post entity (a message sent that only a collection of friends can see), but don't know how to retrieve the guid of the users in that collection.

Thanks in advance
