How do you determine if disambiguation was triggered to activate an action in Watson Assistant

Currently if a user asks a question that triggers a disambiguation, and then clicks an option, I want to be able to determine if the action fired from that button (not the users input).

You can use the variable input.suggestion_id to determine if disambiguation fired.

For example:

<? input.suggestion_id ? "Arrived to action by Disambiguation" : "Arrived directly to action" ?>

Generates this output.
