Is There a Way to Showcase Chat Rooms?

The demo at multiplayer.dev has meant to showcase like all that functionality is there. It does like a mouse, like you can see all the mouse cursors for everybody in the room and then you can post chat messages. And I don't think like the create a room thing is there, but we're limiting people to like five per room. If there's already five people in a room, then you like the room ID will change on you and you'll be the only person in the room if you try and join a room with five people. The typical like Phoenix channels, I, or the old default app before there was live view with the channels chat app didn't persist messages.
