Question from the Symfony 6 test

use Symfony\Component\Notifier\Notification\Notification;
use Symfony\Component\Notifier\NotifierInterface;
use Symfony\Component\Notifier\Recipient\Recipient;

class InvoiceController extends AbstractController
{
    /**
     * @Route("/invoice/create")
     */
    public function create(NotifierInterface $notifier)
    {
        $notification = (new Notification('Such an Invoice', ['email']))
            ->content('You got a new invoice.');

        $recipient = new Recipient(
            $user->getEmail(),
            $user->getPhonenumber()
        );

        ???
    }
}

Which statement should we use to replace ??? and send the notification?

$notifier->send($recipient; $notification);

$notifier->notify($recipient; $notification);

$notifier->send($notification, $recipient);

$notifier->notify($notification, $recipient);
