Sort Event not Firing

[jmorfis]

Hi, I'm using
Laravel Framework 10.48.16
eloquent-sortable 4.40

I cannot get the EloquentModelSortedEvent event to fire.
My Listener/event:

namespace App\Listeners;

use Spatie\EloquentSortable\EloquentModelSortedEvent as SortEvent;

class SortCompletedListener
{
    public function handle(SortEvent $event): void {
        dump($event);
    }
}

EventServiceProvider.php :

namespace App\Providers;

use Illuminate\Foundation\Support\Providers\EventServiceProvider as ServiceProvider;
use Illuminate\Support\Facades\Event;

class EventServiceProvider extends ServiceProvider
{
    protected $listen = [
        \Spatie\EloquentSortable\EloquentModelSortedEvent::class => [
            \App\Listeners\SortCompletedListener::class,
        ],
...

Using Filament to drag/sort. The sorting works perfectly, but the event never fires.
Perhaps I'm overlooking something?
Would love some insight, thanks.
