How do I use RuntimeInitializeOnLoadMethod correctly?

Code (CSharp):

1. using UnityEngine;
2.  
3. public class LoadBeforeScene {
4.     [RuntimeInitializeOnLoadMethod(RuntimeInitializeLoadType.BeforeSceneLoad)]
5.     public void Method() {
6.         Debug.Log("Hello.");
7.     }
8. }
9.  

I'm not sure why this doesn't log anything. How is this actually supposed to be used?

 

Since it's not in MonoBehavior, I don't see why it would run at all. How is it supposed to call the method if there's no LoadBeforeScene objects that can call it?

The documentation all uses static methods, which I assume circumvents this problem, but I believe it would also work if it was just on an in game object.

 

[RuntimeInitializeOnLoadMethod] only works on static and parameterless method
