WLED new method to set palette

Wanting to upgrade to version 2021.12 but my WLED automations need to be changed and I’m a little confused. Any help would be greatly appreciated.

Example says to change palette you use this service call.

service: select.select_option
target:
  entity_id: select.wled_palette
data:
  option: "{{ state_attr('select.wled_palette', 'options') | random }}"

What I’m trying to replace is this

    - service: wled.effect
      target:
        entity_id: light.wled
      data:
        palette: "Jul"

Question with the new version, how do you tell HA what WLED light you’re using. Or does it change all WLED lights?

I’m thinking this is what I need to change to

    - service: select.select_option
      target:
        entity_id: select.wled_palette
      data:
        option: "Jul"

Yes that is correct.

Thanks, I think I was just confusing myself and worried I had it wrong.
