In many cases, a text response is just fine and the AI response question to the user could be answered in text as well.

However, if you are in the business of converting sales as easy, seamless and fast as possible, it makes sense to offer decision buttons next to the response.

A user can simply click on the decision button in order to act for the next step.

Also, it would be very handy to have some standard CTA buttons in place even before the conversation starts. Such as "Book Now", "Check Availability", ""What is my Best Price"? or such on which the AI Workforce can start the task.
