Steps to reproduce the problem:
1. Go to drive.google.com and install a drive app that can open files (e.g. right-click on a PDF, connect more apps, and install Kami)
2. Verify that you can right-click a file in the drive.google.com interface and open it with that app.
3. Open the files app on chrome os (logged into the same account) and attempt to open with the drive app.

What is the expected behavior?
Drive apps that are registered for that file type should be listed in the files app and be openable.

What went wrong?
Only extensions with file handlers are listed, Drive apps are missing.

Did this work before? Yes Not sure- 64 or 65?

I'm not sure if this was an intended change, but I searched and couldn't find any information on it.
