Unknown "asset" function in Twig PHP-CodePudding

I'm having problems importing CSS stylesheet in HTML through TWIG template. The asset() function doesn't seem to be recognised by the compiler. The css file is in app/views/styles and login.html is in app/views. This error occur:

Unknown "asset" function.

index.php

<?php

declare(strict_types=1);

require '../vendor/autoload.php';

use Slim\Factory\AppFactory;
use Slim\Views\Twig;
use Slim\Views\TwigMiddleware;

$app = Appfactory::create();
//twig

$percorso= __DIR__ . '/../app/views';
$twig = Twig::create($percorso, ['cache' => false]);
$app->add(TwigMiddleware::create($app, $twig));


//middleware
require '../app/middleware.php';
$app->addErrorMiddleware(true, true, false);

//rotte
require '../app/routers/routes.php';

// Run app
$app->run();

login.html

composer.json

{
    "require": {
        "slim/slim":"4.*",
        "slim/psr7": "^1.5",
        "selective/basepath": "^2.1",
        "slim/twig-view": "3.3",
        "symfony/asset": "^5.4"
     

    },
    "autoload": {
        "psr-4": {
            "App\\": "app/", 
            "App\\Controller\\": "app/controllers/",
            "App\\Auth\\": "app/middleware/"
            

        }
    }
   
}

I'm using twig-view 3.3 and symfony 5.4.

I tried to import the style by just adding it in the HTML with <style> block and it worked, but I wanted to use a different file just for the style.
