Minimize discord to system tray with alt+F4

I have made a small NVDA add-on which tries to close Discord properly by sending the correct close event.
In case you set up Discord to be minimized to tray when closing main window, it will now do so even with alt+F4.
Soon my add-on hopefully will be added to an official add-on store but for now I give a direct link to the version 1.0.

This version was tested with stable NVDA 2023.3 and NVDA alpha with 2024.1 API.
But I think this add-on will also work on older versions, so be free to alter manifest file and check it.
