Unable to uninstall Microsoft Launcher or Microsoft Family Safety. Apps are installed back automatically

I have migrated my daughters phone from Microsoft Launcher to Google Family Link. Everything works as expected (or even better) but the problem we're facing is that we cannot uninstall Microsoft stuff from the phone -- namely Microsoft Launcher and Microsoft Family Safety. Steps: 1. We locate the application's icon in the app drawer (Android 11, Xiaomi Redmi 11S, MIUI 13) and trying to uninstall it the regular way: 2. We're hit with the confirmation message: 3. After so-called uninstallation process corresponding icon disappears: 4. Only to reappear about 2-3 seconds later: Microsoft stuff (FamilySafety and Lanuncher) are the only apps that we cannot uninstall, we can uninstall any other without any problems. As you can see, a bare Google / MIUI app drawer and launcher is in use. Microsoft Launcher has been (successfully?) removed as a home screen launcher. What we're doing wrong or how can I get rid of it?
