This plugin doesn’t work for me

According to my experience, the plugin doesn’t work as to how its working process is explained in the article which is published by the author. Since I’m taking Elementor as the main tool to customise WordPress pages, a solution that is compatible with these page builders will be the one I was looking for. Unfortunately, I couldn’t make it work as fine as the above article, nor any of the shortcodes provided by the author. It may be caused by the plugin conflicts, but I’d rather invest time in finding other available options instead.
