GitHub Enterprise Server support in the GitHub Copilot app
GitHub made GitHub Enterprise Server support in the GitHub Copilot app generally available. It was an opt-in preview before. You can add your GHES account to the app and work with remote repositories, issues, and pull requests from your Enterprise Server instance.
You have to sign in with a GitHub.com or GHE.com account first. Then open Settings, go to Accounts, choose Add account, and pick GitHub Enterprise Server. The app sends you to your browser to authorize it. To start making requests, you also need to be signed in to a cloud account with a Copilot license, or you can configure your own model provider.
It needs GitHub Copilot app 1.2.0 or later. Cloud sessions aren't available for GHES.
