Issue embedding Calendly

Hello,

I have embedded Calendly in this page my website by using this lines:

<div class=”calendly-inline-widget” style=”min-width: 320px; height: 1000px;” data-url=”https://calendly.com/alfinlibre/charla-alfinlibre”></div&gt;
<script type=”text/javascript” src=”https://assets.calendly.com/assets/external/widget.js”></script&gt;

The issue is that an spinner appears (screenshot attached) and never disappears, which is really confusing for the users.

After contact Calendly technical support, this is their answer:

Our embed has an element with the class of spinner, but your theme also has a class of spinner. Because of this, it looks like our embed it picking up your theme’s spinner class and applying it to the embed.

To fix this, would you be able to modify the name of your spinner class to something besides spinner?

So my question is, is this something doable?

Kind regards.
