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-5334-to-12.4
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick 0ed88d00db646d1ccac6873c150f082843bddd26,d10e216acff6f2128e9fd329eca08849e4094508
# Push it to GitHub
git push --set-upstream origin backport-5334-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-5334-to-12.4.
