I was looking at the documentation and different forums, but I could not find how to do it or show it in Javascript. Could you please help me and share where I can find the implementation steps or how I accomplish this?

Thank you so much. Regards!

You could use the OpenTok Network Test JS module to check network connectivity before people join the video chat or you can use subscriber.getStats() and publisher.getStats() for when people are in the video call. These methods return the following:

Stream quality
Total audio and video packets lost
Total audio and video packets received
Total audio and video bytes received
Current video frame rate

Please keep in mind that you would have to build the widget based on the data returned from the methods mentioned above.
