Pointer size and color changed on Mac is not reflected when sharing screen

[maot]

Hello

I'm using Mac book and OS is Monterey. I changed its pointer size and color because default pointer is really small and hard to see when I sharing my screen. However, some people see it in default size and color. For example, two people out of five see the pointer in default size and color.

Please advise me how to fix this problem.

Thank you.
