COMMUNITY

Hey,
I am trying to build an ecommerce chatbot that can be used to order t-shirts and take payment using Paypal present. But, I would prefer to show the person, the items that he has selected as a cart, to add/remove and then checkout.
How can I do that? Do I use custom variables for this, and how can I display all of his selected products to him in one module??

Any help regarding this is appreciated.

Thanks!
