How to create rest API authentication in Symfony?

Question

symfony

Tell me please. How to create an authentication? How to apply the token correctly?
I tried to follow this documentation https://symfony.com/doc/current/security.html#auth...

namespace App\Controller;

use App\Entity\User;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Routing\Annotation\Route;
use Symfony\Component\Security\Http\Attribute\CurrentUser;

/**
 * The class is for api login
 */
class ApiLoginController extends AbstractController
{
    #[Route('/api/login', name: 'api_login')]
    public function index(#[CurrentUser] ?User $user): Response
    {
        if (null === $user) {
            return $this->json([
                'message' => 'missing credentials',
            ], Response::HTTP_UNAUTHORIZED);
        }
        
        return $this->json([
            'user'  => $user->getUserIdentifier(),
        ]);
    }
}

In this class, I'm trying to log in. And everything seems to be ok.
But as in another class I try to get an authorized user, the result is empty.
For example

class NewsController extends AbstractController
{
    #[Route('/news', name: 'news')]
    public function index(): Response
    {
        /** @var User $user */
        $user = $this->getUser();
        die(print_r($user));
        return $this->json([
            'message' => 'Welcome to your new controller!',
            'path' => 'src/Controller/NewsController.php',
        ]);
    }
}

Security.yaml

                property: username

        dev:
            pattern: ^/(_(profiler|wdt)|css|images|js)/
            security: false
        main:
            lazy: true
            provider: app_user_provider
            json_login:
                # api_login is a route we will create below
                check_path: api_login
            logout:
                path: app_logout

Help me please.
