Class OptimizerChain NOT found

Hi 👋, in RegisterController which comes WITH Laravel, I was want to let the user upload his avatar. everything works well until I installed this package. here is the code

use Spatie\ImageOptimizer\OptimizerChainFactory;

 /**
     * Create a new user instance after a valid registration.
     *
     * @param  array  $data
     * @return \App\Models\User
     */
    protected function create(array $data)
    {
        if (request()->hasFile('avatar')) {
            /* store uploaded file, then get the image path */
            $uploadedImage = request()->file('avatar')->store('public/users');
            /* get instance from `OptimizerChainFactory::class` then pass the $uploadedImage to `omptimize()` method */
            $optimizerChain = OptimizerChainFactory::create();
            $imagePath = asset("storage/users/{$uploadedImage}");
            $optimizerChain->optimize($imagePath);
            /* get the image's hash name WITH its extension */
            $data['avatar'] = Str::after($uploadedImage, '/users/');
        }

        return User::create([
            'name' => $data['name'],
            'email' => $data['email'],
            'avatar' => $data['avatar'],
            'password' => Hash::make($data['password']),
        ]);
    }

the data of the user was saved, the uploaded image was stored successfully also, BUT after I've installed this package, this ERROR Class "Spatie\ImageOptimizer\OptimizerChain" not found happens, WHAT should I do?
