Setup

• Install the pre-release version of GitHub Pull Requests
• Open a clone of a GitHub repo where you can assign issues to Copilot
• Assign an issue to Copilot and wait for it to ask for your review

Testing

• Open the PR webview for Copilot's PR (can be found in the "Waiting for my review " section of the Pull Requests view if you have the default queries.
• Look at the timeline for the PR. Verify that you can see "Copilot started work" and a "Copilot stopped work" entries. NOTE: GitHub has a bug where we're only able to get those two timeline items. If the bug hasn't been fixed yet, then you won't see any other timeline items.)
• Verify that there's a "View session" button on the "started" timeline entry. Verify that clicking it opens the Copilot session in your browser.
