[solved] How do I set up actionable notifications?

I've been reading through the documentation and looked at several tutorials, but I can't get actionable notifications working.

Here's an example YAML that was originally done in the GUI. It's intented to send an actionable notification with two options, and when you click one, it should send another notification to confirm it worked.

It sends the notification fine, and when I tap the button the wait for trigger section in Home Assistant lights up to indicate that it's been triggered. But nothing further happens.

Any help appreciated!

trigger: []

  - service: notify.notify
    metadata: {}

        actions:
          - action: ACTION_NOTIFY
            title: Message me
          - action: ACTION_IGNORE
            title: Ignore
