Chat Bot "Back & Return feature"

Greetings, 

I'm building a chat bot using Zendesk and realized that there is no "go back" or "return first page" feature in it. I want customers to seach for answers using the chat bot cause we integrated lots of data, but if there is no going "back" nor " return first page" option to the last mile customers will end up just checking 1 information, and I dont want that..

Q. I want to know if there's a way to create option "go back/ return home" to previous chatbot message, and how to integrate it or make it.

thanks for checking out.

great day.
