Describe your issue

As the title described. No code called using WorldgenEvents loads when in startup_scripts or any other scripts.

My Code, which is actually your code featured on your wiki:

WorldgenEvents.remove((event) => {
  // remove features by their id (first argument is a generation step)
  event.removeFeatureById('underground_ores', ['minecraft:ore_coal_upper', 'minecraft:ore_coal_lower'])
})

Startup Log:
