Can the Apple Pencil (2nd gen) be endowed with a pointer on screen for the iPad pro (3rd gen)?

The Apple Pencil cannot act as a pointer device.

Plug in your wired mouse, trackpad or Bluetooth device using a Lightning or USB-C port.

There’s no APIs for detecting hovering so you won’t find the functionality in any third-party apps either.
