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-release/3.5 release/3.5
# Navigate to the new working tree
cd .worktrees/backport-release/3.5
# Create a new branch
git switch --create backport-6175-to-release/3.5
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick 6bd07b20b3e55c2fc94da611244a615a4fd2991f
# Push it to GitHub
git push --set-upstream origin backport-6175-to-release/3.5
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-release/3.5

Then, create a pull request where the base branch is release/3.5 and the compare/head branch is backport-6175-to-release/3.5.
