Can AppGyver work with App extensions for bookmarks?

Does anyone know if I can use AppGyver to initiate app extensions and place a button inside the native phone Action menu? Application would add a bookmark to someone’s account.

Specifically:
User is browsing the internet on Safari or Chrome
User finds a webpage they like but want to read later
User clicks the Action menu button
User clicks our App Icon to bookmark, or save for later
That bookmark is saved to the user’s account

Hi! Hmm, I don’t think we have anything like this available at the moment. Not even sure if it’s possible in general, but at least as of now it’s not supported, unfortunately.
