Not found page in laravel-filemanager

[mehdi4467]

hello
I used laravel file manager in laravel 8 but at first, i got some errors. I change the route address in web.php below

Route::get('/laravel-filemanager', '\Unisharp\Laravelfilemanager\controllers\LfmController@show');
Route::post('/laravel-filemanager/upload', '\Unisharp\Laravelfilemanager\controllers\LfmController@upload');

now the file manager will load but the popup will display and write not found.
you can see a video that I uploaded here
