2022 Kona High Driving Lights Connection

I have installed LEDs in my 2022 Kona Elite Electric ( very pleased with them on low beam) and want to install driving lights. We are in serious roo territory here. The 2022 runs HB3 and has no separate high beam circuit. There is a mask in the headlight unit which lifts to enable high beam. Does any one know how to wire the circuit to trigger the driving lights for high beam only?

I have seen a Canbus sensor but am not sure if that is what is appropriate.

 

In case anyone reads this. I have uploaded a diagram sent to me by Kiwi on another forum. The grey wire is the correct one to connect to to trigger the relay. I've tested it and it retains current until high beam off.
