Lipsurf does not work in Paperpile PDF Viewer tab

I use Paperpile, a Chrome extension academic reference tool. When I view a PDF, I cannot use Lipsurf to scroll down on the page.

Wondering if there’s any solution to this.

@jdevi I can see based on the URL there that Paperpile is using its own chrome extension page. There’s no straightforward way for extensions to run on the pages of other extensions. I took a look at their site, and it looks like they have a webapp as well, is it possible for you to use their webapp instead of their extension? If so, LipSurf should work fine there.
