    * Automated cherry-picks do not need subject-matter experts to approve if discussed in the original PR.
    * To trigger the bot cherry pick, either;
        * Apply the correct `cherrypick/release-X.XX` label to the PR, and the bot should pick it up.
        * Use an explicit PR comment command: `/cherry-pick release-X.XX`
