Try creating a file in your public folder (filename.php). Add the code and save
$targetFolder = $_SERVER['DOCUMENT_ROOT'].'/storage/app/public';
$linkFolder = $_SERVER['DOCUMENT_ROOT'].'/public/storage';
symlink($targetFolder,$linkFolder);
echo 'Symlink process successfully completed';
browse the file you created site.com/filename.php
