Not really sure, this saves the file on disk?

Yes, this saved it on disk. But it will delete after the response.
Or change that

$encodeFilename = rawurlencode($filename);
...
'Content-Disposition' => "attachment; filename=\"$filename\"; filename*=utf-8''{$encodeFilename}",

This plan is not use Symfony\Component\HttpFoundation\BinaryFileResponse, but is work too.
