Accelerated Checkout buttons on product page or Cart Page

[fibr_product]

Hi,

We are hosting our product page on a different domain than our Shopify(headless) and want to integrate the accelerated checkout options on that page itself. We are looking to provide the accelerated checkout option either directly on the product page or cart page which is also hosted on the other domain. Need some help in figuring out how to go about this as the other domain is essentially a sales channel.

Thanks
