Speed equivalent for GetCurrentSwing2 in C++?

Hi,
I want to be able to read the current speed of the UPhysicsConstraintComponent.
The function GetCurrentSwing2works perfectly. But I can’t find a function that does the same thing with speed.

Does it exist? Is there a bypass to this or an alternative way to get the angular speed of a PhysicsConstriantComponent motor swing2?

Thank you
