WebXR camera height

I want a similar camera-height of the player in vr-mode and non-vr-mode.
In vr-mode, the world-height of the vr-device (Quest 3) will be added to the height of the camera in the editor.
Is there a simple and elegant solution for this problem?

My hierarchy:

PlayerRoot
     PlayerBody (Entity-Capsule, RigidBody-dynamic, Collision-Capsule) BodyPosition y=1 + Script: CameraController
          PlayerCamera

Looking forward to solve this problem.
