Why are notifications not being sent in Laravel 8?

Question

Laravel

Through the facade I send notifications with a delay

foreach ($orders as $i => $order)
{
    Notification::send($order, (new OrdersDelivered($text_template))
        ->delay(now()->addSeconds($i * 30))
    );
}

The notification itself looks like this

class OrdersDelivered extends Notification implements ShouldQueue
{
    use Queueable;

    private string $text;

    public function __construct($text)
    {
        $this->text = $text;
    }

    public function via($notifiable): array
    {
        return [WhatsappChannel::class];
    }

    public function toWhatsapp($notifiable): WhatsappMessage
    {
        return (new WhatsappMessage())
            ->to($notifiable->client_phone)
            ->text($this->text)
            ->totalOrders($notifiable->total);
    }
}

I made my own channel for sending

class WhatsappChannel
{
    public function send(mixed $notifiable, Notification $notification)
    {
        $message = $notification->toWhatsapp($notifiable);
        WhatsappApi::send($message);
    }
}

All of this works fine as long as you don't use a queue and write implements ShouldQueue. I need to use a queue, but when the handler pulls out tasks, the send method on the channel is not even called. At the same time, all tasks get into the queue

Most likely, you need to start the queue handler, the queue itself does nothing, you need to execute the command
php artisan queue:work
or
php artisan queue:listen
Note that the handler, according to the documentation, must be launched before sending notifications to the queue!
