[1.16.5] How do I set the world to thunder ?

[Toasterkid]

From an entity I can set the world to raining via

entity.level.getLevelData().setRaining(true);

but how do I make thunder with that?

From level I can also see
 

entity.level.setThunderLevel(float value)

and

entity.level.setRainLevel(float value)

but I can't find a description on what those do.
