Comb Hair from "Generate Hair Curves" Modifier? Blender 3.5 Hair

Hi. I used the “Generate Hair Curves” modifier/node on an empty hair curve.
(In Blender 3.5)
It makes hair.
But I can’t comb it.
If I only show rendered objets, the hair disappears.
If I apply it as a modifier, the hair disappears.

How can I use this hair modifier/node to generate hair that I can comb?
I’d like to easily generate hair strands that are evenly spaced out.
So I can more-easily follow this tutorial @1:08:

If there’s an easy answer that I’m missing, please let me know
If not, I guess I’ll just have to manually add hair strands.
