Overview

Show the merged observability metrics on top of the call UI so anyone in the session can see live quality data. This will allow you to see and analyze how our statistics behave during a video session. Based on that you can expand this sample further on your own and set tresholds when to show messages to the user (e.g. about poor connection).
