ROCK Pi 4 : dual screen on android system

Hello, I’m trying to achieve dual screen on ROCK Pi 4C+. I’m using two HDMI displays and I can configure the 2 screens in extended mode. One HDMI with touch (primary screen) and the second HDMI without touch (secondary screen). But my issue is that the touch is only controlling the secondary screen. Even if I use a USB mouse, it is also controlling only the secondary screen. How can I route the touch input to the primary screen appropriately? I’m looking to use 2 touch screen and I would like to route the appropriate touch events to the corresponding screen. How to achieve that?
