How to add SpotLightHelper to a scene

[fnick851]

I am playing with the starter demo and trying to add a SpotLightHelper to the scene. But I cannot figure out how to do it.

Could someone help me with it?

look into dreis useHelper - makes it straight forward. everything that needs constructor arguments is normally driven imperatively, as in you would normally create the spotlight imperatively and then feed it to the declarative helper. but useHelper makes that a little easier.
