I'm developing a PWA that already works fine as such on Desktop and Android. On Android, it can be installed on the home screen and runs offline.
I would expect that this makes the app installable on Chromebook as well, allowing the app icon to be installed into the task bar, for example, without the need for a dedicated "Chrome App" (since I see non technical reason for that).
However, I can't find a way to install my app manually on my Chromebook (Chrome OS 54) - there does not seem to be any "install" command in the menu.
Is this simply not supported (why?) or does this require special settings in the manifest or something?
