Default message not working?

[JoaoCnh]

I've tried running the action with no args to replicate the embed example in the README but no messages is being sent. What is required to send that message?

Yup having just:

      - name: Actions for Discord
        uses: Ilshidur/[email protected]
        if: always()
        env:
          DISCORD_WEBHOOK: ***

Does not make it run anything for me, the step is not even shown in github actions.
