Its self evident that playfab claims to support team based matchmaking only question is how I would obtain that data, thanks :)
Reference:
https://docs.microsoft.com/en-us/gaming/playfab/features/multiplayer/matchmaking/config-queues
"A queue can include team configuration to have the match service assign players to teams."
I assume that this data can be accsessed from some GSDK function once a server has been assigned, correct?
