The Drive API allows access to Comments and Changes on documents but I don't see the new action items feature in the reference documentation.
Is there a way to perform any of the standard CRUD operations on them: get a list of them, get their properties, add new ones, modify them, etc.?
I'm actually interested in doing this through Google Apps Script but I understand that even Comments are only available in the Drive API, so I suspect if there's a way to do it it would be through the Drive API first.
