@pranshuchittora Can I work on this issue?

[jugshaurya]

@khushal87, already working on this kind of issue(here #107), waiting for @pranshuchittora to discuss some of the things.

We can work together on it, once he suggests/clear some things.

Hey, @jugshaurya Sure will be happy to collab. I have seen this issue before that's why I picked up Switch. Would take up more if you want and admins give permission.
