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-13.4 13.4
# Navigate to the new working tree
cd .worktrees/backport-13.4
# Create a new branch
git switch --create backport-776-to-13.4
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick 54d86563143e9b9a883ac16117fcf4d64c6981cf
# Push it to GitHub
git push --set-upstream origin backport-776-to-13.4
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-13.4

Then, create a pull request where the base branch is 13.4 and the compare/head branch is backport-776-to-13.4.
