Chope
Please wait for next release. Otherwise, you can refer to my workaround code.
In my forum system, users simply view images, so I changed the code.
File: vendor/flagrow/upload/assets/templates/image.blade.php
<div class="flagrow-download row">
<p>
<img src="{@url}" title="" alt="" />
</p>
</div>
Please note that it's a temporary solution because this code ignores additional features of this extension.
