Hopefully I'm asking this at the right place. League of legends recently added the option to join a club. Clubs still use the XMPP protocol just like before for their public chat rooms: XMPP for public rooms.
For public chat rooms, you connect through the "lvl.pvp.net" server.
For the private clubs' chat rooms, the server is now "pgc.pvp.net".
My problem is that I can't figure out how to find the room address to connect to a club. The clubs are private rooms. Only someone that is part of the club can view and chat in the club. Unlike for a public chat room, where the address is simply: pu~"Channel name hashed and no capital letters", a club address is a UUID and therefore, unlike public rooms, it's impossible to figure out the room address from the club name.
Riot is fine with people connecting to the XMPP server from outside apps, but they haven't provided an easy way to find the UUID for a club room.
How do I find what it is for my club?
