I am creating a chatbot for a pizzeria, at the end there is a confirmation for the order. If the user says no, i would like the user to say what he wants to change, and either the ai task or whatever can change the variables for the answer that the user said. Exemple: Bot: Pizza with mushrooms/pepperoni. Is this what you order? User: No Bot: What do you want to change? User: i dont want mushrooms but ananas Bot: I got it, so you want a pizza with ananas and pepperoni. Is this right ? User: yes . In this exemple, i want the bot to understand what variables need to be changed, change them and give the answer as provided in the exemple. Is this possible?
