How to emit and listen custom socket events.

Question

I have a web socket server where 8 players can send data and they are updating the field of play. So... When they go into a special area to fight i want that this 2 players in, to just listen their area socket events.
Nodejs:

 const SERVER_STATUS = "server_status"; 
 function sendServerStatus(ws) {
     let buffer = gdCom.putString(JSON.stringify({ data: players }));
     ws.emit(SERVER_STATUS, players);
}

Godot Client

ws.connect(SERVER_STATUS, self, "_serverStatus")
...

func _serverStatus(response):
    print(response)
    print("receive")

So is there any way to do this????
Emit from a server custom events an listen them with Godot WebSocketClient
Its like a classic behavior of rooms on a Socket.IO server
