            Hey there and thank you for opening this pull request! 👋🏼

            We require pull request titles to follow the [Conventional Commits specification](https://www.conventionalcommits.org/en/v1.0.0/) and it looks like your proposed title needs to be adjusted.

            Details:

            ```
            ${{ steps.lint_pr_title.outputs.error_message }}
            ```

      # Delete a previous comment when the issue has been resolved
      - if: ${{ steps.lint_pr_title.outputs.error_message == null }}
