Apple Pencil X iPad mini 4

The iPad Mini 4 is pre Apple Pencil days and the iPad Mini 4 lacks the necessary screen hardware layer needed for the Apple Pencil to interact with the iPad’s screen.

You will need to seek out a third party alternative smart, Bluetooth stylus.

Sorry & Best of Luck to You!

iPad mini4 does not support Apple Pencil - as it lacks the necessary “active” display hardware.
