LattePanda 3 Delta 12.5 IPS Touch Display touch wont work

Hello, how do i need to connect the new 12.5 Inch Display to the Delta3 to get the touch to work please? I connected it with the provided HDMI Cable and tried additionally to connect an USB Cable.

I downloaded the Drivers and installed them.

I can see it in the DeviceManager as a unknown Device using Goodix Touch HID Drivers  but the touch doesn´t work.

Please help
