USB Touch Monitor not recognized properly in PIE Preview

I am using a Dell Touch Monitor as second screen (connected HDMI and USB) to preview the touch application I am building.

I noticed that UE does not pick up the touch input when previewing in selected viewport or PIE (new window).

The only I got it working is by enabling “use mouse for touch” but this only acts like an emulator and only supports one finger.

Is there anything else I am overlooking when building/testing with a connected touch screen?

Thanks
Felix
