product-page Add a secondary button in product page

Curious how to add a secondary button on a product page.

Here is an example: https://www.bigcatcreative.com/templates/gigirose-squarespace-template#!/~/

Thanks!

Some options to achieve this

If all products use button with same link, just add it to Footer or add to Not Linked Page, then we will give code to move it next to Add to Cart on all products

If use different button, just add a Button Block in Additional Info > Then share link to a product, we will give the code to move its position.

With Example Above, they use Standard Page, not Products, so they can add anything.

Thank you! Any idea how they were able to include the "add to cart" button there? I have a form people will need to fill out when they click add to cart.
