Laravel is not sending Pusher Events to my Vue.js frontend - laravel

Question

I have a Vue.js separated project from a Laravel backend in many tutorials I see a Laravel + Vue.js but I have a Vue.js SPA separated and I don`t know what I doing wrong.
I already make the configuration on front end, this is it:
const pusher = new Pusher(configMain.PUSHER_APP_KEY, {
cluster: configMain.PUSHER_APP_CLUSTER
});
const pusherChannel = pusher.subscribe('teste');
pusherChannel.bind('my-event', function(data) {
console.log(data);
});
When I use the debug console in PUSHER and send an event, it works fine I receive it. But when I try to send an event from my backend Laravel project it doesn`t work.
BROADCAST_DRIVER=pusher
PUSHER_APP_ID=********
PUSHER_APP_KEY=********
PUSHER_APP_SECRET=********
PUSHER_APP_CLUSTER=********
I already set the keys and change the driver, in config broadcasting i have this:
'pusher' => [
'driver' => 'pusher',
'key' => env('PUSHER_APP_KEY'),
'secret' => env('PUSHER_APP_SECRET'),
'app_id' => env('PUSHER_APP_ID'),
'options' => [
'cluster' => env('PUSHER_APP_CLUSTER'),
'encrypted' => true,
],
],
I created an event in Laravel that is this:
<?php
namespace App\Events;
use Illuminate\Broadcasting\Channel;
use Illuminate\Broadcasting\InteractsWithSockets;
use Illuminate\Broadcasting\PresenceChannel;
use Illuminate\Broadcasting\PrivateChannel;
use Illuminate\Contracts\Broadcasting\ShouldBroadcast;
use Illuminate\Foundation\Events\Dispatchable;
use Illuminate\Queue\SerializesModels;
class MyEvent implements ShouldBroadcast
{
use Dispatchable, InteractsWithSockets, SerializesModels;
private $message;
/**
* Create a new event instance.
*
* #return void
*/
public function __construct($message)
{
//
$this->message = $message;
}
/**
* Get the channels the event should broadcast on.
*
* #return \Illuminate\Broadcasting\Channel|array
*/
public function broadcastOn()
{
return new Channel('teste');
}
public function broadcastAs()
{
return 'my-event';
}
}
And when i execute this in my backend:
event(new MyEvent('hello world'));
dd("ENTROU");
My front doesn't receive it, I must do something that I don't see it?
