Trait 'Exportable' not found in Laravel Excel?

I have imports:

namespace App\Http\Controllers;

use Maatwebsite\Excel\Concerns\FromQuery;
use Maatwebsite\Excel\Concerns\WithTitle;
use Maatwebsite\Excel\Facades\Excel;
use Exportable;
use Maatwebsite\Excel\Concerns\WithMultipleSheets;

And class:

class ArchivingController extends Controller implements WithMultipleSheets
{

    use Exportable;

}

Why I get message:

Trait 'Exportable' not found
