[BUG] Can't select input on TVMode (12.2 stable)
**Describe the bug**
Just updated my iPhone to iOS 12.2 (stable), plugin is on v0.6.2, haven't tried TVMode before (never had any beta's installed on my iPhone). I cannot select any input from the Home app.

**To Reproduce**
Added "TVPlatformMode": true, to config.json, restarted Homebridge (0.4.46). Visible as TV in Home-app but cannot select input (grayed out? - see screenshots). Inputs are visible when opening the accessory settings though.

**Expected behavior**
List of activities to select as input.
