title: Book an appointment via a bot - which cards/attachments?
body: <p>I'd like my bot to take the user through the process of booking an appointment. I want almost exactly the flow show on the home page of the <a href="https://dev.botframework.com/" rel="nofollow noreferrer">https://dev.botframework.com/</a></p>
  
  <p><a href="https://i.stack.imgur.com/i6QoX.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/i6QoX.jpg" alt="enter image description here"></a></p>
  
  <p>However I cannot seem to find the right attachment types to represent the list of buttons or the follow up details with the 'Book now' button. Can anyone tell me which types of attachment/card these are?</p>
