Here my export files

namespace App\Exports;

use Maatwebsite\Excel\Concerns\FromArray;
use Maatwebsite\Excel\Concerns\WithHeadings;
use Maatwebsite\Excel\Concerns\Exportable;

class TestExport implements FromArray, WithHeadings
{
    use Exportable;

    public function headings(): array
    {
        return [
            'id',
            'name'
        ];
    }

    public function array(): array
    {
        return [
            1,
            'John Doe'
        ];
    }

return (new TestExport())->download('test.csv', \Maatwebsite\Excel\Excel::CSV, [
