Pop-Up Lightbox button for Calendly

Hi there,

I am trying to create a "Book Now" Button to open up pop-up Lightbox for my Calendly Calendar. Is it possible to create in markup/code a button with pop-up?

Thanks :)

I was looking for an answer to this too but couldn't find one! So I made this code from the calendly one, and am posting it here in case it helps someone else.  Obviously change the style to suit your needs. If anyone has a better way to do this let me know. This is my first squarespace site so I may have missed an easy trick!

<!-- Calendly link widget begin -->
<center>
<link href="https://assets.calendly.com/assets/external/widget.css" rel="stylesheet">
<script src="https://assets.calendly.com/assets/external/widget.js" type="text/javascript"></script>
 <a href="" onclick="Calendly.initPopupWidget({url: 'YOUR CALENDLY LINK GOES HERE'});return false;"

    style="padding: 21px 34px;
    font-weight: 600;
    letter-spacing: 1px;
    font-family: sans-serif;
    font-size: 15px;
    font-weight: 500;
    font-style: normal;
    text-transform: uppercase;
    letter-spacing: .15em;
    color: #fff;
    background-color: #89c8cd;
    border-color: #89c8cd;
    text-decoration:none;
    border-radius: 3px;"
   >YOUR TEXT HERE</a>

</center>
<!-- Calendly link widget end -->

Thank you @Fonty - this was helpful! 👍
