Is it possible to use the PDF viewer on shared documents?

I shared some folders to other people but when they try to open them so we can all annotate the same PDF, Paperpile opens the file using the default chrome viewer.

I have tried this as well and I think isnt possible yet, since the PDFs are saved in your personal drive. And therefore other people would be granted access to your drive via paperpile?
