Loading external calendar with html widget in elementor

Hello there,

Can someone help me with add this code to html widget? Because it’s not working. It must show an external booking calendar. Is there something with this code? I must use it only on my webpage https://bauerhaus.nl/, otherwise it’s not working.

For privacy reasons i changed the name of the data widget and url of script source. I put this in a html widget:

<div class=”cp-widget” data-widget=”calendar_ScHtS” data-widgetype=”detail”></div>

and this script in a javascript snippet in the footer:

<script src=”https://www.chlts.com/extern/js/cp-widget.min.js”></script&gt;

The page I need help with: [log in to see the link]
