Question Is there a shared ID for one MCSession?

Hi, I wonder if there is some sort of shared sessionID for one MCSession/collaborative session, that will be identical for all users currently sharing one specific AR experience in the same place? I have unique sessionID's per device, but is there a way for me of knowing which shared session that user is in?

In my use case, the users need to communicate to a server to get specific content. I need to make sure to only send content to one user per shared MCSession, so I need some sort of identifier. Otherwise, I risk sending content to several users in one shared session.

 

Thanks for the response! I dug into this and no there doesn't seem to be any shared ID for an ongoing MCSession. My solution to this, in case anyone would run into a similar issue, is to store a temporary list with all users sessionID's, and check the sessionID's each user finds through ARParticipantManager against this list to determine which shared AR session they're in.
