[Help] Does Unity only support one touchscreen on Windows?

Hello. Recently, I am developing a multi-screen Unity project.

My computer is connected to 3 touch screens. My computer uses Windows system, and the Unity version is 2021.3.6f1.

When I export the Unity project as an EXE program, only the touch function of the first touch screen is normal, and the other two touch screens do not work. I searched on the Internet and found that Unity seems to only support one touch screen in the Windows system.

Is there a workaround for this?
