I know this question has been asked link here.
But it's two years ago. The new version 1.0 has been released for a long time. The official docs still don't have everything on it.
I think maybe someone have summarize some study notes or whatever useful.
This is what I collected in stackoverflow:
1.Get a room's clients list or this
2.Emit to a specific client or this
3.Get a list of all the namespaces
Any feature or help would be appreciated
