Windows 11: Notifications vanishes after few seconds.

[SWinxy]

Back in mid-2021 I submitted a feature request
<https://bugs.openjdk.org/browse/JDK-8266423> to add new APIs for toast
notifications on macOS and Windows *without* using SystemTray. It's
something I'd like to implement. Apple introduced its notification APIs
<https://developer.apple.com/documentation/foundation/nsusernotification?language=objc>
in
macOS 10.8. Never worked with the WinRT before, though.
