Finished the Wiki post for now friends:

I like how organised it looks, good job!
Just one question: what is a presence session?

Ah, you hit it. I have really no idea. Translating this didn’t help me. Epic itself left it to “true” in the ShooterGame.
It guess i will ask the Staffs on the AnswerHUB. (:

EDIT: Ok, the documentation says: “Whether to display user presence information or not”. I opened an answerhub post, because i
still have no idea what this should do. Maybe i can hid User Information about the creating user for people searching this session
when i set it to false.

EDIT2: Ok, it seems like with this bool, you can get information about the playing Users in this Session:

But i have no idea how to use this correctly. This is a thing that goes beyond the basic setup that i learned till now ):
