[ERROR] Web Server for Chrome Extension Is Outdated : WebRTC

[Err999]

Dear WebRTC developer,
Your page https://codelabs.developers.google.com/codelabs/webrtc-web#2 doesn't work right.

It is outdated (Last updated Nov 20, 2020) and your Chrome extension, Web Server for Chrome, is no longer supported and doesn't work after December 2022.

May I ask where the correct website for WebRTC is?

Thank you.
