In Unreal using Multiplayer::Lobby API,
What is a ResouceId? The docs vaguely describe this as "The name of the resource to subscribe to." What is "the" resource?
What is the PubSubConnectionHandle? I just make a new, arbitrary UUID myself and pass it?
If these 2 items are not arbitrary, why do the docs not guide us to let us know what to actually do with these?
