Hey @ahmedmemon785, thanks for making the change, however, it seems like autoformatting hadn't been run causing your PR to return a large diff, I've just pushed a change to the master branch committing the autoformatted changes, if you pull and update your PR, that'd show a more correct diff of what you were looking to update.

Also, could we see a screenshot of how the change looks? Thanks!
