          Hi @{{pull_request.user.login}}.

          Just a little hint from a friendly bot about the best practice when submitting pull requests:

          > Don't submit pull request from your own `main` branch. It's recommended to create a feature branch for the PR.

          *You don't have to change it for this PR, just make sure to follow this hint the next time you submit a PR.*
