Connect launch modal for existing button

Hi all,
I created a launch modal for a specific product.
I want this modal to be shown only when the product will be added to cart.
I already have a button from the product-template, but how do I set the modal to be shown when this button is clicked?

Great Q @ItaySviri - right now the launch modal template fully depends on you clicking the provided button. Will keep your use case in mind for future modal templtes though!
