Chrome OS support in Chromium extension

Exploring whether it's feasable to add Chrome OS support to the extension.

Relevant fragments from feature request per mail:

Thanks for the great app. I was just wondering if there was any way to allow the PDF Viewer to work when I open files using the File Manager in ChromeOS (Using a Chromebook) and opening Google Drive Files.

I'm attaching two screenshots showing how one is opened with the default Chrome PDF viewer. The other is opened with your extension. You will notice the URL is different for them, one is locally stored on my Chromebook, the other is on my Google Drive account.
