@Syed-Ali-Abbas-Zaidi, I'd love to help push this forward. Do you mind resolving conflicts? Also, is there a particular reason the PR is still a draft?

Thanks!

This PR is currently blocked due to React v17 upgrade that is the reason I have marked it as Draft.

Yes, I have already notified the owning squad (aurora) they are currently working on testing these changes locally. Once testing is done this PR will be good to go.
