I read through the documentation, and I understand how players obtain a matchmaking ticket, then poll it until they have a matchid, which contains the IP of the server to connect to.
However, on my server, how can I validate that a particular incoming player has legitimately gone through the matchmaking process (instead of, e.g. hacking their client to connect to a particular server by IP directly)?
The legacy system has a redeem ticket concept, is there a way to do this with the new system too?
