How to view center of mass

On my search for an answer I have found this thread which ends with the statement that it is now possible to view the center of mass of an object. But where? What steps do I need to take to see the center of mass?

Create a blueprint and build your object

Drag n drop the blueprint on the level editor

Top windows - Show - Advanced - Mass Properties

Enable wireframe view, set center of mass from the blueprint

You can see some icon, its the center of mass
