Transforming 2D object with respect to UI

So I’ve been trying to make this 3d isometric game where I have set my camera rotation as x: 33.2 y:44.5, which means that when I move something along the x-axis, it also changes the values of my y-axis and z-axis after scripting. In easy words, I want to move my 2d sprite horizontally with respect to the UI instead of considering the world axis. Is there a possible solution to move it like that?

// Update is called once per frame
void Update()
{
    transform.position += new Vector3(beatTempo * Time.deltaTime, 0f, 0f);
}

.

If you want to move something in relation to the camera, then you can simply transform the movement vector by the camera’s rotation;

private Camera cam;

private void Update ()
{
    //We don't want to access Camera.main every frame, so get it once and store it
    if (!cam)
        cam = Camera.main;
    //Then, just multiply the movement vector by the camera's rotation to rotate it. Now, it will be defined relative to the camera's rotation.
    transform.position += cam.transform.rotation * new Vector3 (beatTempo * Time.deltaTime, 0f, 0f);
}
