Webflow + Shopify Buttons

Hey, i’m building a store on Webflow with Shopify Buy Buttons. I’m waiting to get the Webflow +Ecommerce tool but till that i’m running my store over Shopify BB.

Now there is a solution video on that (https://www.youtube.com/watch?v=C-5B6PumMc4), the problem is that my Buy Button differs from the video example.
I sell clothing so there are 2 additional selection fields (Size/Color) required before adding to cart.

Can someone help me with implementing The BB to my CMS product page?

Hi. Did you figure this out? I know that Weblow added E-commerce already, but I still want to use Shopify for the back-end.
