Though this work could be done in other ways too, I decided not to edit the code much and do the work in least possible differences.
Is this approach right?

Thanks @utkarsh-maheshwari 😄 Can you add it to the changelog (together with your previous PR for which we skipped that step) before merging? Both PRs can be mentioned in a single bullet point with two pr links

No problem, we have the checklist on the pr template because we all forget if we don't see it there. Thanks for the PR!
