Messaging: Hide text entry field from End Users on certain Step types

We need to be able to hide / disable the End User's text entry field in the web widget at key points in our answer flows.

For example, at certain "Present Options" steps, I don't want customers to be able to type in their answers; we need them to exclusively use the buttons in the widget in those steps.

Currently, customers are typing in freeform answers, which frequently sends them into a different (wrong) flow. This leads to an extremely frustrating user experience.

Ideally, I'd like to be able to toggle the text entry field visibility at the individual step level for these step types:

• Present Options
• Ask if Question Resolved

It could be as simple as a little toggle / slider within the Configuration of these step types:

       Text Entry Field Visible?  (true/false)
