Connecting Relume Buttons to CMS Collections in Webflow

Hi all, I have what seems like a very basic ecommerce component question ; How do I connect the relume add to cart and go to checkout buttons on my products page to my cms collections & cart? They are in a form block so webflow won't let me replace them with webflow's add to cart button? Feel like i'm missing something. Checked finsweet doc linked to the component and they don't seem to relate to the add to cart and buy now buttons. Thanks ! https://preview.webflow.com/preview/roguesgallery?utm_medium=preview_link&utm_source=d[…]&itemId=6740604882a32723d29a7bbf&locale=en&workflow=preview
