Missing Mic function is Apple TV integration

I was finally able adding my Apple TV via the integration option, but there seems no functionality for the microphone. Anyone successful with this?

Secondly, I have another device (Swisscom TV Box) which also has a mic function. Suggestions on how to setup the UC’s mic button for said device.

Received the UC a few days ago. Well built but not that ergonomic in the hand compared to the Harmony Elite. Eventually somehow understood the setup process.

The voice function is not yet implemented and scheduled for Q4: Software roadmap
