How to download xlsx file in laravel?

I use the library as a means of generating Excel documents. Only I need to either save the file to the root/storage/app/public/export/file.xlsx directory, or immediately download the file in the browser. Everything is implemented in Laravel 9. Tell me how to write the code correctly?

My code, now:

use PhpOffice\PhpSpreadsheet\Spreadsheet;
use PhpOffice\PhpSpreadsheet\Writer\Xlsx;
...
    $spreadsheet = new Spreadsheet();
    $activeWorksheet = $spreadsheet->getActiveSheet();
    $activeWorksheet->setCellValue('A1', 'Hello World !');
    $writer = new Xlsx($spreadsheet);
    $writer->save("file.xlsx");
        

The file is saved to a folder 'public'. Help me, please!
