In replace media js/css are not enqueue in the page

In my website the replace media page has not the js/css in the page so is not usable.

I added those 2 lines in the media-replace.php:

<script src="<?php echo plugin_dir_url(dirname(dirname(__FILE__))) . 'assets/js/replace-media.js'; ?>"></script>
    <link href="<?php echo plugin_dir_url(dirname(dirname(__FILE__))) . 'assets/css/replace-media.css'; ?>"/>

Investigating a bit in the admin the method to enqueue the files is executed but they are not in the page. Only with that change I was able to get that working.
