如何在c＃windows应用程序中实现“第二个鼠标光标”？

I actually don't want it to be a "real" mouse cursor, i.e. no need for ability to click on buttons, select text etc. It should just look like a cursor (or kinda like it) and be able to move around the app's window (no need to go outside). It will be controlled by the computer, and the user should be able to use the mouse as usual during this time.I actually don't want it to be a "real" mouse c
