add a clear variations button on product page

Hello,

I’m looking for a way to add a clear button hat will reset the selection made by the user previously.

I searched the forums, it seems than in some themes the button is already there.

The website is running Divi/woocoomerce and Variation Swatches for WooCommerce.

Thanks for showing me the direction and helping me understand all this.

The page I need help with: [log in to see the link]
