To enable USB debugging on the Lenovo Tab P12 you first have to enable developer options. This is easily done by going into "settings" and "about tablet". You then have to tap 7 times on "software version", to enable this feature. Developer options can then be found under "general settings" usually at the very bottom of the page. From there you should be able to find USB debugging which allows you to connect a USB cable and copy files to and from your tablet to another device. This demonstration also works on any Lenovo device running on the android ZUI version 16 or similar operating system.
