How do you access the editor event args?

I need to access the “object” on the OnGrab event. How is this done in the method I call?

Example method, using dynamically created args

private void DoObjectGrab(object sender, InteractableObjectEventArgs e)
    {
        if (e.interactingObject == controllers.left)
        {
            holdControl = controllers.left.GetComponent<VRTK_ControllerEvents>();
            stringControl = controllers.right.GetComponent<VRTK_ControllerEvents>();

            holdActions = controllers.left.GetComponent<VRTK_ControllerActions>();
            stringActions = controllers.right.GetComponent<VRTK_ControllerActions>();
        }
        else
        {
            stringControl = controllers.left.GetComponent<VRTK_ControllerEvents>();
            holdControl = controllers.right.GetComponent<VRTK_ControllerEvents>();

            stringActions = controllers.left.GetComponent<VRTK_ControllerActions>();
            holdActions = controllers.right.GetComponent<VRTK_ControllerActions>();
        }
        StartCoroutine("GetBaseRotation");
    }
