Sorry I've never actually answered this thread. Typically I try to answer right away. If not it's a sign that it's complicated. And everything that happens in the Google Docs integration is complicated for so many reasons...
What exactly is the use case? You have written a document in Google Docs and your boss reads the document and wants the PDF from your library? Or does your boss writes a document himself and wants the link?
Or let's forget your boss for a minute, what was your use case when you first submitted the request? It appears it was about getting a faster link to the PDF from your library, right? That means for you as a Paperpile user who has the access to the library and the extension installed.
I'm happy to comment further once I understand better what the goal is.
