Pretty simple. Adding an arrow will allow users to hide the leaderboard and only show themselves on it.
This is what it would look like after pressing the arrow to hide the other users.
This is where the arrow would be. (The arrow looking up means the leaderboard of all the users is showing. Pressing it will make it look down and hide all the users except you.)
This would really help when theirs a lot of players in the server and the board feels like it’s in your face.
