Please provide your Laravel/Lumen version. Laravel Framework Lumen (8.2.3) (Laravel Components ^8.0)
Which release version of this package are you using? v2.8.1
What did you do? If possible, provide a recipe for reproducing the error.

<?php

use Illuminate\Http\Request;
use SwooleTW\Http\Websocket\Facades\Websocket;

/*
|--------------------------------------------------------------------------
| Websocket Routes
|--------------------------------------------------------------------------
*/

Websocket::on('connect', function ($websocket, $request) {
  // in connect callback, illuminate request will be injected here
  $websocket->emit('message', 'welcome');
});

What did you expect to see? Emit the 'message' event as it's shown above. I'm using socket.io v4.0 on client side and it connects properly to server, even I'm able to print a console message on connect event, but when I try to emit an event from server it fails and if I emit an event from the client side to the server, the server doesn't detect it.
What did you see instead?
