Python could use newer WinRT APIs [6], in particular ToastNotification 
class [7] which provide richer interface for the toast notifications. 
The package name ‘toast’ hints it uses the newer APIs.

Perhaps, Microsoft changed how they handle notifications in Windows 11. 
In Windows 10, the notifications created with a Java app remain in 
Action / Notification centre.

Java uses Shell_NotifyIcon [8] function that has been available since 
Windows 95.
