Option to open PDF from sidebar add-on

I have been using Paperpile for a few months already, but I just recently started to use the sidebar add-on.
In the sidebar, I was surprise to see that when I find an item from my library, there is no button or link to directly access the PDF associated with this item. It would save me a lot of time to have the option to directly open my PDF from Google Docs instead of opening the app.
Thank you and keep on the great work,
