I clicked a link on https://github.com/features/copilot that deeplinks into VS Code with the following URI: vscode://GitHub.copilot. If I don't have that extension installed, the feature works great!

Actual

If I already have the extension installed (say that I didn't realize what the link should do), VS Code opens but nothing happens.

Expected

There is some indication that the URI was processed, maybe a toast that says <Extension Name> already installed
