Get steer angle

Hi,

I have a two wheel vehicle and i would like to get continuously the steer wheel angle. If i use the get socket rotation i measure the angle between socket and the world coordinates but i want to know the how much is the steering angle.
I am aware of the Get steer angle node but i do not know how to use it. Is this the correct approach and how to or do you have any other? (I am using UE 4.25)

Thanks in advance
