Login route with parameters in url before

I am trying to create my laravel website app with an original login route pattern. I need to have the custom name and alias in the URL because I have created a kind of portal where all customers have their own landing page. In my previous website version, I used sub-domain names but it's too heavy to manage.

This is what I want:

The login URL has to be:

• my-app.com/{customer_name}/{customer_alias}/login
• my-app.com/{customer_name}/{customer_alias}/home
• my-app.com/{customer_name}/{customer_alias}/list-product

I have tried some stuff, but after login in, I never got routed to the full URL like I want. In the best case after login in, I'm redirected to https//home and I don't understand why!

My Route file : Web.php

Route::get('/{customer_name}/{customer_alias}/login',  [ LoginController::class, 'login'])->name('login');

// The app part when user are logged
Route::prefix('/{customer_name}/{customer_alias}')->middleware( ['auth', 'access'] )->group(function () {

    Route::get('/', 'DashController@index');

}

My MiddleWare access

<?php

namespace App\Http\Middleware;

use App\Customers;
use Closure;
use Illuminate\Support\Facades\Auth;
use MongoDB\Driver\Session;

class Access
{
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {

        $customers = null;

        if( session('customer_alias') != "" ){

            $customer_alias= session('customer_alias');

        } else {

            $customer_alias= $request->route('customer_alias');
        }
        
        $customer = customer ::where( 'customer_alias', $customer_alias)->first();


        if(!$customer ){


            abort(404);

        } else {

            session(['customer_id' => $customer ->id]);
            session(['customer_name' => $customer->name]);
            session(['customer_alias' => $customer->alias]);

        }

        return $next($request);

    }

My Auth\LoginController.php

<?php

namespace App\Http\Controllers\Auth;

use App\Customers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use Illuminate\Foundation\Auth\AuthenticatesUsers;

class LoginController extends Controller
{
    /*
    |--------------------------------------------------------------------------
    | Login Controller

    | This controller handles authenticating users for the application and
    | redirecting them to your home screen. The controller uses a trait
    | to conveniently provide its functionality to your applications.
    |
    */

    use AuthenticatesUsers;

    /**
     * Where to redirect users after login.
     *
     * @var string
     */
    protected $redirectTo = '';

    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        $this->middleware('guest')->except('logout');
    }

    protected function authenticated()
    {
        $url = explode('.', $_SERVER['HTTP_HOST'])[0];

        if($url ==''){
            abort(404);
        }

        return redirect(session('customer_name')."/".session('customer_alias')."/home");
    }

    protected function credentials(Request $request)
    {
        $credentials = [
            $this->username() => strtolower($request->input($this->username())),
            'password' => $request->get('password'),
        ];

        return $credentials;
    }

    public function showLoginForm(Request $request, $customer_name, $customer_alias)
    {
        $this->redirectTo = '/' . $customer_name .'/'. $customer_alias;

        $customer = Customer::where( 'alias', $customer_alias)->first();

        if( !$customer ){
            abort('404');
        }

        return view('auth.login', compact( 'customer ' ) );
    }
}

Thanks for your help, I'm very confused about it.
