Could you please clarify if this works as expected on iOS 13.6.1?

These metrics don't exist in iOS 13.6, many new metrics have been added since iOS 14. We have cut a ticket for adding the missing metrics (comparing to Chromium and w3c webrtc-stats) and has been closed (https://bugs.webkit.org/show_bug.cgi?id=212668), some of the metrics have been added (verified in iOS 14 beta 5), but there are still some important metrics that are missing.
