Ask and Save User email in custom Chatbot

Hello, I would like to integrate a chatbot that asks the user for their email and stores it in a list. maybe also other data. Is this possible? What would be the best way to include this feature? I would like to build Real Estate Agent Coach, which helps users to get help with selling their home and get advice on this site here https://eigenheim-invest.de/. The site is built on WordPress.
