incompatibility with Buy Now plugin

Hi.
I’ve noticed that when using this plugin alongside a plugin called “Buy Now Button for WooCommerce”, the popup of added product doesn’t appear.
Currently, these are the versions I have for both plugins:

YITH WooCommerce Added to Cart Popup -> 1.6.3

Buy Now Button for WooCommerce -> 1.0.0

Wordpress -> 5.8

WooCommerce -> 5.5.2

Is there a known issue between these 2 plugins? Is there a way to have them both working properly together? Alternatively, is there another “Buy Now” plugin that does work with the popup plugin?

Thank you.
