Messing with VFX Graph time scale/playback rate

Unity Forum user Olmi did a nice code snippet for this

https://forum.unity.com/threads/what-is-the-right-way-to-pause-particles.837889/


using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.VFX;

public class vfxgraph_playrate : MonoBehaviour
{
    [SerializeField] float timeScale = 1.0f;
    [SerializeField] VisualEffect VFX;

    void Start()
    {
        VFX = GetComponent<VisualEffect>();
    }

    void Update()
    {
        VFX.playRate = timeScale;
    }
}

NEAT AS HECK. WHY ISN'T THIS A NODE IN VFX GRAPH?
