This module will show a popup with products right after a product has been added to the cart.
To enable, please access Customizer > WooCommerce > Product page > Components in summary > Add to cart (block) eg: https://d.pr/i/m5QpVi .
The options will allow to specify what type of products to show, either Upsells, or various other sorts of combinations.
By default it’s not enabled on catalog grid pages however you can change that with a simple toggle.
A quick demo can be seen here https://d.pr/v/s3ziWS .
