Maintainer checklist

• The commit messages for the remote branch should be checked to make sure the contributor's email is set up correctly so that they receive credit for their contribution
  • The contributor's name and icon in remote commits should be the same as what appears in the PR
  • If there's a mismatch, the contributor needs to make sure that the email they use for GitHub matches what they have for git config user.email in their local activist repo

I’m closing this PR because it unintentionally includes commits from another branch . I created a new branch directly from main for the typo fix and will open a new PR for it. Sorry for the confusion!

I thought this had been merged, or was that in a downstream project, @OmarAI2003?
