Packaging Inserts Asking for Reviews

I am designing my packaging insert to include in my packaging, in which I ask the customer to review the product. I understand the general rules of asking for reviews (can’t offer discounts to review, etc), but I’d like to know how people go about telling people HOW to review the product. Is there a link you tell them to follow, instruct them to review you on Amazon (which is where I want the reviews), or give more specific instructions? Or do you expect the customers to know what to do without going into more detail then, “give us a review”. Appreciate any input, thanks!
