Harmony buttons on dashboard - how?

Configuration Frontend
1

I’m a complete beginner with using code, but it looks like I’ll need to learn.

I’ve got the Harmony Hub integration added, and I can run an activity or power on/off my kitchen TV and amplifier. I can’t control the volume though.

I can see the “commands” for volume listed in the Harmony.conf file, so I’m guessing there is way to use these “commands” from the dashboard, but where do I start?
Just 2 simple buttons on the dashboard is what I’m looking to achieve.

Complete beginner at this, so an “idiot’s Guide” needed.

Example:

    - service: remote.send_command 
      target:
        entity_id: remote.harmonyhub
      data:
        device: 66619196
        command: Select

Device and command come from harmony_*.conf

Thanks.
So, would I just type that into the code editor after adding a “button” card?

tap_action → perform-action:

Sorry, I’m not understanding how I add the service, target and data information to the button? Do I do this in the UI, the code editor for the button, or the raw code editor for the whole dashboard?
As I said, this is the first time I’ve tried to do things that aren’t already there as “entities”

Thanks for that, got it working!
I missed the “action” “remote:send command” option on the drop down list
