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_40 release-3_40
# Navigate to the new working tree
cd .worktrees/backport-release-3_40
# Create a new branch
git switch --create backport-63621-to-release-3_40
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick 32946552e355d859ed289cf4d863ec420a3c0a15,ec501a5699fd37698f17d3b04cd7949b2870f1f2
# Push it to GitHub
git push --set-upstream origin backport-63621-to-release-3_40
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-release-3_40

Then, create a pull request where the base branch is release-3_40 and the compare/head branch is backport-63621-to-release-3_40.
