@paul2009 thank you for your reply 🙂 It is compatible with squarespace, I have succesfully added the button on other pages, but I want to add it to every single product page as a button before the "add to cart" button. If I add it in the "page header code injection" it of course appear as a button in the header. And I need it to appear as a single button on every product page - do you know how to do it?
My website: https://www.idemcopenhagen.com/
and the code for the button:
<div class="saia-widget-container"></div>
<script id="saia-mtm-integration" async src="https://mtm-widget.3dlook.me/integration.js" data-public-key="NTI1MQ:1rwiCk:jDqe0ZOqcbZo5xcKgfrwJQEBSADaxf3Io5TSJt6xvJ4">
