Cannot run extension

I've installed a Chrome extension on Microsoft Edge (Chromium) to play HLS video. I've tried on Microsoft Edge (Chromium) and it works fine. The HLS URL is http://localhost/hls/taiguo/playlist.m3u8 and the Microsoft Edge browser displays the full URL as: extension://ekcifneimckhkjdfklkkpdlnckcjhmke/index.html#http://localhost/hls/taiguo/playlist.m3u8.

I want to use the code sample from Getting Started with WebView2 (developer preview) to play the media in a Windows program. If I call Navigate(...) using the .m3u8 URL as follows:
webviewWindow->Navigate(L"http://localhost/hls/taiguo/playlist.m3u8");
the application will download the playlist file, but not play the media automatically. If I use the full extension like:
webviewWindow->Navigate(L"extension://ekcifneimckhkjdfklkkpdlnckcjhmke/index.html#http://localhost/hls/taiguo/playlist.m3u8");
the app will display the following error message:
ekcifneimckhkjdfklkkpdlnckcjhmke is blocked
Requests to the server have been blocked by an extension.
Try disabling your extensions.

I hope someone can tell me what is the correct way to run extension using WebView2. Thanks in advance!

Start with the Getting Started with WebView2 sample and the Navigate(...) call described in the issue, then check WebView2 documentation for extension:// navigation and Chromium extension support. Done would be a documented, reproducible way to run the extension in a Windows WebView2 app, or a confirmed limitation with an alternative path.
