Howdy folks --

Saw something intriguing in an Instacart email in Gmail today:

I know there's this Reveiw Action in the Gmail schema, but it looks quite different and is served up in the inbox, not in the email itself:
https://developers.google.com/gmail/markup/reference/review-action

Anyone seen anything like this before? Or know how to make it happen?
