Sylius - ERROR {"code":500,"message":"Could not resolve argument $em

Question

I need to retrieve my repository in my function in a Custom Controller I've created but it gives me the following error:

{"code":500,"message":"Could not resolve argument $em of \"App\\Controller\\LicenceController::getlicencecodecrm()\", maybe you forgot to register the controller as a service or missed tagging it with the \"controller.service_arguments\"?"}

sylius_ressource.yaml:

sylius_resource:
    resources:
        ############## Licence ##############
        app.licence:
            driver: doctrine/orm # You can use also different driver here
            classes:
                model: App\Entity\Licence\Licence
                repository: App\Repository\LicenceRepository
                form : App\Form\LicenceType

services.yaml :

    App\Controller\LicenceController:
        autowire: false
        public: true

LicenceController.php :

`    public function getLicenceCodeCrm(Request $request, EntityManagerInterface $em)
    {
        // $repo = $this->get('App\Repository\LicenceRepository');
        $repo = $em->getRepository(Licence::class);
        $criteria = $request->query->get('phrase');
        $q = $criteria['search']['value'];

        $items = $repo->findByNamePart($q);

        return new JsonResponse([
            '_embedded' => [
                'items' => $items,
            ]
        ]);
    }`

LicenceRepository :

    public function findByNamePart(string $codeCrm, ?int $limit = null): array
    {
        return $this->createQueryBuilder('o')
            ->andWhere('o.codeCrm LIKE :code')
            ->setParameter('code', '%' . $codeCrm . '%')
            ->setMaxResults($limit)
            ->getQuery()
            ->getResult();
    }
