Android app on ChromeOS

I am running the Android App on a Chromebook, it works locally but the “casting” icon does not appear. It works fine on my Android devices. Can this be fixed?

Can you access your Tablo using the my.tablotv.com website in a Chrome browser on your Chromebook? Instead of using the Android app, which was designed for smartphones, tablets, and Android TV boxes such as the Nexus Player, etc.
