Studio's GitHub integration has been upgraded to use a GitHub App. An admin installs the app once for your GitHub organization, and every team member can immediately push code, create branches, and open pull requests from the Studio editor — no individual GitHub account setup required.
Visit Studio > Settings > GitHub to install the GitHub App for your organization
After installation, a repository list shows which repos are accessible to your team
Use Manage Repositories to control access directly from the settings page
To remove the integration, use Uninstall & Disconnect to fully remove the GitHub App
