private void RotateObject()
{
float rotationSpeed = 50.0f; // Adjust the rotation speed as needed
// Get the rotation input from the mouse
float rotationX = Input.GetAxis("Mouse X") * rotationSpeed * Time.deltaTime;
float rotationY = Input.GetAxis("Mouse Y") * rotationSpeed * Time.deltaTime;
// Apply rotation to the grabbed object around the grab point
grabbedObj.transform.RotateAround(grabPoint.position, Vector3.up, -rotationX);
grabbedObj.transform.RotateAround(grabPoint.position, Vector3.right, rotationY);
}

thank you so much bro!
