I found the fix to this.
Click START button, then Settings.
Select SHARED EXPERIENCES
Enable NEARBY SHARING (My Devices Only)
Enable SHARE ACROSS DEVICES (My Devices Only)
created an account just to confirm and thank you.
In addition to this, what helped me get it working was, turning on background services for "your phone"
you can find this on your windows pc > settings > background apps >your phone > on
I'm using pocophone f1 running android 10
