You'll want to make sure that your GitHub app has a callback url configured that redirects to your localhost application (http://localhost:3000/api/auth/callback/github). If you start the application with the dev npm script it will handle forwarding webhooks to your application making use of the github-app-webhook-relay-polling library without the need to configure smee as long as you have your local .env configured properly.
