Add a "back to store" button to a Woocomerce Product page

Hi,

we need a back to Shop Button to the Productpage in Woocomerce. The Button should show OVER the Product-Picture.
We’ve already tried the solution from this post (https://kriesi.at/support/topic/how-to-add-a-back-to-store-button-to-a-product-page/).

Unfortunately, the button next to the “Shop” is displayed here.

Thanks a lot!

Thilo
