How to make WidgetComponent look like billboard?

How to make WidgetComponent look like billboard?
I make Widget Component (A) with Widget Blueprint. (like nameplate).
I call A’s SetWidgetSpace(EWidgetSpace::World), so it looks like 3d mesh.

I call SetWorldRotation like Tesla does with PlayerCamaraManager and GetComponentLocation and FindLookAtRotation.

But, because the widget looks at camera, it doesn’t align like billboard or 2D widget, but it faces to center (camera) if the camera location is like TPS.

How can I make widget rotate to face at screen?

SetWidgetSpace(EWidgetSpace::Screen);
