Create a multistep subscription

Hello everyone,

I am trying to create a multistep subscription for a website, but a condition is to have a add to cart for the product the user want to subscribe and with the multi step form I can’t add the “add to cart” button, here is the link to the view Webflow and to the design I created with Figma.

Thanks for the help

Webflow: subscription page

Figma file: Subscrition flow.
