Target class [Spatie\Permission\Middlewares\RoleMiddleware] does not exist

Okay so I'm kinda new to laravel and I'm trying to use Spatie for roles and permission but this error happened, even though I've written the class name in kernel.php here :

<?php

namespace App\Http;

use Illuminate\Foundation\Http\Kernel as HttpKernel;

class Kernel extends HttpKernel
{
    /**
     * The application's global HTTP middleware stack.
     *
     * These middleware are run during every request to your application.
     *
     * @var array<int, class-string|string>
     */
    protected $middleware = [
        // \App\Http\Middleware\TrustHosts::class,
        \App\Http\Middleware\TrustProxies::class,
        \Illuminate\Http\Middleware\HandleCors::class,
        \App\Http\Middleware\PreventRequestsDuringMaintenance::class,
        \Illuminate\Foundation\Http\Middleware\ValidatePostSize::class,
        \App\Http\Middleware\TrimStrings::class,
        \Illuminate\Foundation\Http\Middleware\ConvertEmptyStringsToNull::class,
    ];

    /**
     * The application's route middleware groups.
     *
     * @var array<string, array<int, class-string|string>>
     */
    protected $middlewareGroups = [
        'web' => [
            \App\Http\Middleware\EncryptCookies::class,
            \Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
            \Illuminate\Session\Middleware\StartSession::class,
            \Illuminate\View\Middleware\ShareErrorsFromSession::class,
            \App\Http\Middleware\VerifyCsrfToken::class,
            \Illuminate\Routing\Middleware\SubstituteBindings::class,
        ],

        'api' => [
            // \Laravel\Sanctum\Http\Middleware\EnsureFrontendRequestsAreStateful::class,
            \Illuminate\Routing\Middleware\ThrottleRequests::class.':api',
            \Illuminate\Routing\Middleware\SubstituteBindings::class,
        ],
    ];

    /**

     *
     * Aliases may be used instead of class names to conveniently assign middleware to routes and groups.
     *
     * @var array<string, class-string|string>
     */
    protected $middlewareAliases = [
        'auth' => \App\Http\Middleware\Authenticate::class,
        'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,
        'auth.session' => \Illuminate\Session\Middleware\AuthenticateSession::class,
        'cache.headers' => \Illuminate\Http\Middleware\SetCacheHeaders::class,
        'can' => \Illuminate\Auth\Middleware\Authorize::class,
        'guest' => \App\Http\Middleware\RedirectIfAuthenticated::class,
        'password.confirm' => \Illuminate\Auth\Middleware\RequirePassword::class,
        'permission' => \Spatie\Permission\Middlewares\PermissionMiddleware::class,
        'precognitive' => \Illuminate\Foundation\Http\Middleware\HandlePrecognitiveRequests::class,
        **'role' => \Spatie\Permission\Middlewares\RoleMiddleware::class,**
        'role_or_permission' => \Spatie\Permission\Middlewares\RoleOrPermissionMiddleware::class,
        'signed' => \App\Http\Middleware\ValidateSignature::class,
        'throttle' => \Illuminate\Routing\Middleware\ThrottleRequests::class,
        'verified' => \Illuminate\Auth\Middleware\EnsureEmailIsVerified::class,
    ];
}

Did I miss something or write something wrong? (By the way, I use Laravel v10.30.1 if that helps)

I try to access a view using this routing : Route::middleware('role:super-admin')->get('/dashboard', [AdminController::class, 'index'])->name('admin');

The vendor frame thingy tells me this : \public\index.php : 51 require_once

Below is the line the error happened :

$app = require_once __DIR__.'/../bootstrap/app.php';

$kernel = $app->make(Kernel::class);

**$response = $kernel->handle(**
    $request = Request::capture()
)->send();

Try using \Middleware\ instead of \Middlewares\

'role' => \Spatie\Permission\Middleware\RoleMiddleware::class,
'permission' => \Spatie\Permission\Middleware\PermissionMiddleware::class,
'role_or_permission' => \Spatie\Permission\Middleware\RoleOrPermissionMiddleware::class,
