Show Standard Balloon cann't work

[casper-rinnai]

I run sample code

and foud that show standard balloon cann't work,

but show custom balloon working properly.

my os is windows 11

I have looked into the TaskbarIcon class and found that it uses WinApi.Shell_NotifyIcon to show standard ballon.
I guess this windows api does not act on Win11 as it does on Win10. It is probably due to the permission management issue on Win11.

I'm very sorry that I don't have Win11 to test it. Just some suggestions, Hope that helps.
