How to show selective UI features?

I have a UI that needs to either show icons on a timeline view or not based on user profile. How can I show for some users and not for others? For example : the Sports Admin team needs to see the scores of all teams over time in the view (showing all years visually) but the players (when they login to the same web app) only see the timeline view with their team's performance over the years (not other details for a particular year). How can I achieve this? I am using Angular JS and javascript

I have looked into role based SSO login and show selectively and also cookies. My goal is faster performance - meaning the page needs to load fast.
