Question OnEnable not triggering in script on prefab.

I have a script on a prefab, and I want to create some editor specific behavior. However, OnEnable doesn't trigger at all. I am using the [ExecuteAlways] attribute on the script. The Prefab is not present in the scene, is that a problem? It's also not in the Resource folder, but moving it there didn't seem to make it work regardless.

Is it possible for this to work, and if so, how?

 

You can use InitializeOnLoad attribute on a static class, I think that's what you're looking for. You should use ExecuteAlways when you have the instance on the scene.
