How to add Camera Shake?

I would like to add a Camera Shake to one of my CameraActors.
I am able to find the CameraShake Option → But how can I apply the shake to the camera itself?


My camera is not animated yet. But even to a static camera, it should be possible to add a shake, right?
Soo… what am I missing and doing wrong?

Thank you very much for your help!
