I see the "SubscribeToLobbyResource" API but it doesn't have a dynamic delegate that is fired every time a lobby invite is sent to a client. How can I bind to a lobby invite so I can raise a UI event to set up an accept or decline state for the lobby invite?
Also the docs say that this API is not ready to be called by customers. So for now what is the correct solution to making sure a UI element pops up when a player gets an invite?
EDIT*
According to this forum post a required parameter to subscribe to invite notifications is not built into playfab. Is there a tutorial out there on how to implement Azure PubSub into a game?
