Laravel Namespace Resource Controller Routing

I was working on a laravel project. The following is the code of my UserController:

<?php

namespace AppHttpControllersBackendAdminUsers;

use AppModelsUser;
use IlluminateHttpRequest;
use SpatiePermissionModelsRole;
use AppHttpControllersController;
use IlluminateSupportFacadesSession;
use AppRepositoriesInterfacesUserRepositoryInterface;

class UserController extends Controller
{
protected $userRepository;

    public function __construct(UserRepositoryInterface $userRepository)
    {
        $this->userRepository = $userRepository;
    }
    public function index(Request $request)
    {
        $users = $this->userRepository->all($request);
        return view('backend.admin.users.index')->with(compact('users'));
    }
}

My routes in route.php file are:

<?php
use IlluminateSupportFacadesRoute;
use AppHttpControllersAuthLoginController;
use AppHttpControllersBackendAdminDashboardController;
use AppHttpControllersBackendAdminUsersUserController;

Route::group(['namespace' => 'BackendAdmin', 'prefix' => 'admin'], function () {
    // login for super admin
    Route::middleware('guest')->group(function () {
        Route::get('/login', [LoginController::class, 'index'])->name('login');
        Route::post('/login', [LoginController::class, 'login'])->name('login.submit');
    });
    Route::middleware(['auth', 'role:Super Admin'])->group(function () {
        Route::get('dashboard', [DashboardController::class, 'index'])->name('dashboard');
        Route::get('logout', [LoginController::class, 'logout'])->name('logout');
        Route::resource('users', UserController::class);
    });
});

But whenever I goto the users route by using http://localhost/ecommerce-app/admin/users. The following error occurs:
Target class [BackendAdminAppHttpControllersBackendAdminUsersUserController] does not exist.
And in debuggar the following routing come:
BackendAdminAppHttpControllersBackendAdminUsersUserController@index
I want a bit assistance on how to use namespace for the resource controller and routing
