Accessing world generator resource settings

[dymen1]

I want to access the world generator settings when a specific event runs (the run code at event is working)
But I can't find documentation on how to access world generator resource settings (e.g. iron ore)
I have found some hints about objects that could hold this information:
data.raw["resource"]["resource_name"]
and
game.setting
so does anyone know how to access those settings? (or if at this stage it is even possible to access them)

*edit: typo -_-
