Hi, we want to add any missing subscription code to the themes. As far as I know, if I do a Subscription add, I need to add the code to dipslay plans in the product page, show selected plan in the cart, on my account, etc.
Some new themes already offer support for all these things except on product page. So I would like to know what's the process to add this code. Because each theme is unique.
you need to use the Selling Plan Group liquid object: https://shopify.dev/api/liquid/objects/selling-plan-group
And the selling plan liquild object: https://shopify.dev/api/liquid/objects/selling-plan
