When that button is clicked, it will show the modal based on the information you add like the seller id and checkout-data
I created a demo for it on theme creator
Everything seems to be working on our side but I haven’t actually bought anything since I haven’t used checkout-page before. Can you try to actually use it @FrancoisD like to buy / sell things and report back?
Once we confirm everything is working, I’ll move this to the theme category.
I also left some comments in the code to explain how this was put together.
