How to add a button/link below Add To Cart button?

Hi,

Here is what I am looking for:

Add a button/link below ADD TO CART button, it should open a new page where I want to run some custom logic.

I am new to Magento so still struggling with terminology. Could you please guide me here about how can I add a new page and link it to a button/hyperlink?

Add the link into product.info.options.wrapper.bottom or product.info.extrahint container.
