Play a particle system when Time.timeScale = 0?

Hey! I have a particle system explosion that I want to play when the player dies. The idea that is that everything else pauses but the explosion continues, like the Pacman animation when you die (everything freezes and the pacman death animation plays).

Trouble is, it won't work. I know Time.timeScale = 0 pauses everything, and I've tried using this script to combat that, but it doesn't seem to be working:

 void Update()
 {
     if (Time.timeScale < 0.01f)
     {
         particleSystem.Simulate(Time.deltaTime, true, false);
     }
 }

I have also tried this, but it doesn't work either:

 private ParticleSystem pSystem;
 
 public void Awake()
 {
     pSystem = gameObject.GetComponent<ParticleSystem>();
 }
 
 public void Play()
 {
     pSystem.Simulate(Time.unscaledDeltaTime,true,true);
 }
 
 public void Update()
 {
     pSystem.Simulate(Time.unscaledDeltaTime,true,false);
 }

I have tried this code with a script that is attached to my explosion particle system prefab, which is instantiated at the player's position when you die.

Thanks!
