Turn on only lights with a specific label

I’ve spent time searching and reading HA docs and I still can’t figure out…

How do I create a Script to only turn on lights with a specific label?

Assign labels to the lights, then use the light.turn_on service with the label as the target.

service: light.turn_on
data: {}
  label_id: special_lights

Thanks. So easy, but I could not find that.
