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_7 release_3_7
# Navigate to the new working tree
cd .worktrees/backport-release_3_7
# Create a new branch
git switch --create backport-4846-to-release_3_7
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick dcadcc58b2985d5cdca2c64d62dfd93cddb2a7b6,1d8eaf67a76329c46d074e6492e28f3aff2cb7b9,3c32d7d81f86a7dbf2008e4beb490629a11ade90
# Push it to GitHub
git push --set-upstream origin backport-4846-to-release_3_7
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-release_3_7

Then, create a pull request where the base branch is release_3_7 and the compare/head branch is backport-4846-to-release_3_7.
