Compatibility with Lumix Flow for S5ii

The lumix flow app looks super promising and when it was announced I jumped on it (mostly because I really don't want to spend money on an external monitor lol).

Sadly the app is only compatible with the S1Rii. The app description states that it will be available for the S5ii, S5iix and GH7.

My question is: does anyone know when it will be compatible with the S5ii?
