title: Hide the soft keyboard in Facebook Messenger Bot
body: <p>Hi I'm writing a Facebook Messenger bot that has a few nice looking card actions - that end up taking up a large portion of the chat window. The problem is that the soft keyboard on phones such as iPhone and Android still displays, constraining the visible area of the chat to an even smaller window, obscuring the card.</p>
  
  <p>Is there a way I can send some sort of specific JSON down in my bot messages to indicate to FB Messenger that the keyboard should be hidden until the user clicks back into the message entry area?</p>
  
  <p>Thanks.</p>
