Great article, but I've come across a need that doesn't seem met by the current 'Ask for Approval' action and I have no idea why since it seems like a no-brainer.

The person who actually Approved or Rejected isn't readily available as an output of the Action.  I realize there's ways to get it, but that's more Activity real estate that doesn't need to exist IMO.  Do you know why that isn't a thing (or maybe I'm missing something obvious)?
