Hello,

I do not believe you will help me, but I will try.
I found a way to achieve what I wanted. With this code: https: //wordpress.stackexchange.com/questions/355057/add-a-custom-button-with-custom-link-after-add-to-cart-for- every-product

I can upload links to the products and after adding to the cart a button appears with the link Used after add to cart hook.
All you have to do is show about the variations.
This button is not currently displayed for variants.
Can you help me?
