设置权限给dir。 和它的文件ftp laravel

Question

How can I set permission read, write, and execute to a folder and its contents once it is created via ftp.

$ftp = Storage::disk('sftp')->put($clientName . '/' . $fileNameToStore, fopen($uploadedFile, 'r+'), 'public');

This is what I tried, and some users cannot copy the file from the path.
