laravel seeding db through routes

I want to run a seeder command through web.php here is my code

Route::get('permission-seeder/{class}',function($class){ Artisan::call("db:seed --class=$class"); });

I am getting this error

Symfony \ Component \ Console \ Exception \ CommandNotFoundException
The command "db:seed --class=PermissionSeeder" does not exist.

Although this seeder exists in the directory

can anyone sort it out
