C#. How to implement a notification counter when the program is minimized?

Question

C++ / C#

Good afternoon.
I am developing a chat program. Almost all chat programs, when minimized to tray or simply to the dashboard, when new messages appear, a circle with a number appears, showing the number of messages.

thanks in advance
