How to make your chatbot more connected through ecommerce

Hello guys, how can i make my shopping assistant for an ecommerce store be able to add products to user's carts, redirect users to other pages on the on the store, know which product page the user is on, and more all by its self? If you don't get what i mean, the attached video shows a shopping assistant made by hellorep.ai which does all of these functions mentioned as shown in the video. how can i make my voiceflow chatbot do this stuff too? they are really good features and if added, it would make voiceflow the go-to ecommerce AI shopping assistant software
