Didn't spread props, as it wasn't in before issue code and all functionalities isn't known, so can't decide if spreading props is required. Just for now, added CoreBox and CoreTypographyBody2 in valid props

Currently fixed existing functionality and added one extra functionality to start timer on clicking button.
Extra functionality is not complete.
