Help Needed: Quest3 Bluetooth HID Protocol and Key Mapping Documentation

I have successfully established a Bluetooth connection and implemented basic HID protocol functionality, but I'm unable to determine Quest3's parsing rules for button events, encountering difficulties in key mapping. I hope official support or experienced developers can provide guidance or documentation references.

For example:

• In Quest3's Bluetooth HID descriptor, what are the corresponding characters/bytes for mouse movement, clicks, scroll wheel actions, etc.?
• Is there any publicly available official protocol documentation or reverse-engineering reference?

Any help would be greatly appreciated!
