Feature for displaying custom device on wrist

[DangerKiddy]

Feature Description:
Possibility (feature) to add custom device via OSC or Websocket to the wrist, where I can specify base64 image, current battery level and is device currently charging (battery state).
I'm developing application for displaying Headset's battery info (For Pico 4/4 Pro and Meta Quest in future) and would really like to be able to display it on wrist, instead of attaching window to the hand or somewhere else

Additional context:
In OVR Toolkit I've attached window to my wrist (since it don't have mentioned feature too) for demonstration:

Headset battery is coming natively when running through anything that pipes the data to SteamVR, as long as the Device class is HMD and battery info exists, anyways.
