How to connect H6 pen?

Recently purchased Hi10x with H6 pen support but cannot figure out how to connect it. Pen has charged for over 12 hours and does not show up on Bluetooth connectivity list. Pen came with no documentation.

Please tell me the serial number

Hello I have the same problem I think.

The serial number of the tablet is Hi10X Q128GH62040949. Not sure where to find the serial number for the pen if that’s what you need.
