Adding product to the cart when site is embeded in an iframe

Hi There,

Wondering if anyone a can give me some pointers on how I might add a product to the cart when it is embeded in an iframe.

Trying to use webflow in part as an ecommerce backend for a virtual tour.

I can add the product to the cart on the actual website but not from the embeded iframe.

Tour link - [Ecommerce Test]
open product page by click the info icon on the blue highlighted couch

Product add to cart - [Vir2ual Tour 2]
