Using echo listeners

Hello, is it possible to listen for events using Echo as described here: https://laravel-livewire.com/docs/2.x/laravel-echo ? I can't seem to get it to work. I have the following in my "Page" (/App/Filament/Resources/ResourceName/Pages/Page.php)

    public $showNewOrderNotification = false;
 
    // Special Syntax: ['echo:{channel},{event}' => '{method}']
    protected $listeners = ['echo:orders,OrderShipped' => 'notifyNewOrder'];
 
    public function notifyNewOrder()
    {
        $this->showNewOrderNotification = true;
    }

    public $showNewOrderNotification = false;
 
    // Special Syntax: ['echo:{channel},{event}' => '{method}']
    protected $listeners = ['echo:orders,OrderShipped' => 'notifyNewOrder'];
 
    public function notifyNewOrder()
    {
        $this->showNewOrderNotification = true;
    }

I can see that my event is being triggered in my Ably account, but I don't see that Filament is adding any code that would subscribe the browser to the "orders" channel. Am I missing something or is this not supported?

Debounce / Lazy on Markdown Field not working

I've created a markdown field with the following settings:

Forms\Components\Markdown::make('question')
  ->default('Question?')
  ->reactive()
  ->lazy()
  ->afterStateupdated(function ($state) {
      Debugbar::log($state);
  }),

Forms\Components\Markdown::make('question')
  ->default('Question?')
  ->reactive()
  ->lazy()
  ->afterStateupdated(function ($state) {
      Debugbar::log($state);
  }),

The lazy() option does not appear to have any effect and causes the field to become basically unusable since it updates constantly while you're typing. However, if I switch this field to be a standard TextArea field like this:

Forms\Components\Textarea::make('question')
  ->default('Question?')
  ->reactive()
  ->lazy()
  ->afterStateupdated(function ($state) {
      Debugbar::log($state);
  }),

Forms\Components\Textarea::make('question')
  ->default('Question?')
  ->reactive()
  ->lazy()
  ->afterStateupdated(function ($state) {
      Debugbar::log($state);
  }),

The lazy() option works as expected and the field isn't updated until the field loses focus.
