How to use MIUI+ on supported devices on xiaomi.eu ROM

MIUI+ allows you to control your smartphone from your Windows PC, seeing it's screen and using Keyboard & Mouse. It also syncs several things like Photos, Calendar and Messages.

MIUI+ only works for a limited set of devices. If your device is supported, but you use xiaomi.eu ROM, some libaries are missing from the ROM and screen sharing won't work.

There's a chinese developer, who made a Magisk module, that adds back many of the removed features/apps/libraries to xiaomi.eu.
