@Ankit-Singla Please don't open pr for the issue which already has a pr. There is no good in doing same thing multiple time. Instead of that you can focus on issue which doesn't have pr. :)

@namangupta01 Sorry, I thought no one was working on it since no one claimed the issue and the issue wasn't assigned to anyone.
Regarding the PR, I opened another one because checks failed in your PR #2182 .

@Ankit-Singla No issues! There are plenty of fto-candidate issue if you want you can work on them since i think you are new to the codebase. Just comment there to claim the issue and to check if somebody is working on that or not.
