To backport manually, run these commands in your terminal:

# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add .worktrees/backport-12.4 12.4
# Navigate to the new working tree
cd .worktrees/backport-12.4
# Create a new branch
git switch --create backport-4573-to-12.4
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick 0466ad4d293ce14ebdf447c5fcb5316c9e95bdae
# Push it to GitHub
git push --set-upstream origin backport-4573-to-12.4
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-12.4

Then, create a pull request where the base branch is 12.4 and the compare/head branch is backport-4573-to-12.4.
