i used Intervention Image with laravel 8

I have a small problem in Intervention Image in config/app

'providers'=> Intervention\Image\ImageServiceProvider::class,

'aliases' => 'Image' => Intervention\Image\Facades\Image::class

in route

use image;
Route::get('/test', function () {

$img = Image::make('foo.jpg')->resize(300, 200);

return $img->response('jpg');});


error : Undefined type 'Image'

after run I get an error saying:Image source not readable
