@V21-vani Could you please add the Jira ticket you worked on? I also noticed some conflicts could you resolve them? And make sure to follow the pull request guidelines then we start review. Accidently closed ignore.

@harshsomankar123-tech Hi! Sorry for missing the Jira ticket, I made this as part of getting familiar with the codebase. Should I create a new ticket for this or link an existing one(though it doesn't match entirely with what I've done)? I've already resolved the conflicts, will also go through the PR guidelines and update accordingly!
