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-1294-to-12.4
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick 792e430136a19abd54e75574847e6150caab5a5c,eb63e7f5a7ca15fc430f352362debe8a63feb142,47314aa2ec00c2ac6868df070bf78e419950c6d7,5a996b25d73232aa0a8304b9be6bed6a7572c9a2
# Push it to GitHub
git push --set-upstream origin backport-1294-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-1294-to-12.4.
