Question regarding the possibility of a lobby matchmaking system

Hi, only just started looking into this about 20 minutes ago so I really don’t know any more than you probably, but one thing I have got is that you can do a “create session”, which will make an instance of the game that users can join to, I think that this can then be done multiple times.
(OFC I see this was sent in January, but felt it may help anyone else finding this)
