It’s a server resource, I can’t provide any screenshot.
It’s up to you to broadcast WebSocket messages if needed. In your server script, add an event handler for
WebSocketServer:onMessage and then broadcast received message to clients (you can add
TriggerClientEvent("your:clientEvent", message) inside the event handler).
Same thing applies for RCON, if you need a command, add a new RCON command to your resource and trigger what ever you want.
