the requirement is similar to that after a computer installs Tencent PC Manager, pressing the win key will create an extra area on the right side of the start menu
can you develop the application? press the win key to achieve this effect (the display area of your program can pop up with the start menu and can be resident all the time)

some people provide ideas, monitor the win key, users press the win key to pop up their own application window, press the win key again to hide
my idea is not advisable, scientific practice should be related to the development of uwp applications.

ask for guidance
