How to animate some property of custom `QQuickItem` based class using C++?

Question

As we know, Scene Graph has special multithreaded v-sync aware render technology.
Also QtQuick has special C++ classes specified with QSG* prefix names and are strongly recommended to be used only those classes inside QQuickItem.

So is it ok to use regular (old?) C++ Animation Framework classes such as QPropertyAnimation in QQuickItem classes?

How I can animate some properties inside QQuickItem using C++ without breaking Scene Graph performance/rules?

Thank you
