Hi @hz
We can't debug extensions in VS code Edge extension.
I know you feel inconvenient when debugging Edge extensions, but AFAIK the only way to debug Edge extensions is debugging them in Edge browser.
You can sideload the extension in Edge according to this doc then debug it. You can also refer to this doc about debugging extensions as Edge now use the same chromium engine as Chrome, so you can refer to the Chrome doc.
If you have any issue when developing an Edge extension or have any feedback about Edge extension, you can refer to this doc about where to request help and provide feedback.
