Unity HDRP: How to rotate the skybox

With the new Unity HDRP the skybox and environment settings from the lighting bar have disappeared and made way for a different way to tackle these, with the Volume Settings gameobject.

Is there a way to call the rotation value from this gameobject in code? I mean the rotation knob thing not the game object rotation itself as it would just rotate the gameobject and not the skybox itself.

public Volume volume;
private HDRISky hdriSky;
private float hdriRotationSpeed = 20;
private float rotation = 0;

    void Start() {
        volume.profile.TryGet(out hdriSky);

    void Update()
        if(Input.GetMouseButton(1)) {
            if(Input.GetKey(KeyCode.LeftAlt)) {
                float angle = Input.GetAxis("Mouse X") * hdriRotationSpeed;

    private void rotateHDRI(float angle) {
        rotation += angle;
        while(rotation > 360) {
            rotation -= 360;
        while(rotation < 0) {
            rotation += 360;
        //hdriSky.rotation.value = rotation;

With this script you can rotate the hdrisky by pressing right mouse button + left alt and moving the mouse. hdriSky.rotation.value = rotation; does not work for me, but i saw it in other answers to same questions.
