I seem to be missing or misunderstanding something regarding PlayFabs parties API, I can't seem to figure out how a client is supposed to retrieve a list of other active parties. This seems to have me stuck on translating a function I used to have with Xbox Live, but I can't figure out what the parity of the function is here.
Currently parties seem to use cloud scripts to store their descriptors in temporary groups, but I can't retrieve a list of groups. The documentation itself suggests using matchmaking to prepare a party with a group of players, but there appears to be no function to retrieve a list of active matchmaking lobbies (plus I would apparently require out of band communication to send the lobby descriptor and it lists no example on how to go about doing that). Alternatives I could think of is having a single individual group to read and write active games to, but the documentation itself extremely advises against this incase I had, say, 1000 players pull this list at once (not that I expect that to happen a lot, but it's plausible). Title storage itself is potentially too slow and not ideal for real time lists either.
What are my options for implementing this?
