Hello,
unfortunately, it’s not possible. The buttons can be added to archive pages through this option:

However, they will show up only for single products. Variable and bundle products are excluded, I’m also going to test grouped products and probably exclude them too. The reasoning is that the customer must first select a product variation before adding to the cart. Your buttons for variable products are standard WooCommerce buttons that lead to the product page on click, so the user has no possibility to select variation on the home page. It makes the quantity buttons useless for variable products without custom solutions to manage variations from the home page.
It would be problematic to adjust the plugin to work correctly with custom solutions, usually build-in in the theme, where probably half of these solutions have their own quantity buttons anyway and are all done in a different way. If I include such a solution within the plugin, there will be infinite problems with presenting all possible variation choices in a visually appealing way for each theme.
What I suggest is trying out Quick View plugins that may offer something very close to what is needed.
Best regards,
Ryszard
