Please add color code to quickly identify that the user is connected to vpn

On earlier iPhones, if you were connected via VPN the little VPN indicator would appear in the status bar at top.

With the iPhone X, when you connect via VPN, the little VPN indicator appears for a moment and then disappears. The only way to confirm that you are connected to vpn is by constantly checking the control center and the worst part is if you forget that you are connected to vpn, you will not even realize that you connected to vpn for several days until you either accidentally notice in control center or when you notice erratic behavior in network connection.

Instead adding a color code (like you see for calling, screenshot below) in background (where you see network and battery indicators) would make much more easy to identify
