I am trying to replace the 'Add to cart' text with an image or an icon but can't figure out how to do it using the shortcode variations.
Solution:
It is not possible to add an icon or text directly inside the add_to_cart_text attribute. Instead, use custom CSS to add it as a background image. Provide the URL where the shortcode is used and the URL of the image for further assistance in creating a CSS starting point.
