I successfully configured GitHub auth in the local backstage app, and everything runs smoothly during login. However, after containerizing the app with Docker and deploying it to my PC, I encounter an error when trying to log in: "Origin 'http://localhost:7007/' is not allowed." What should be my homepage URL and callback URL on GitHub? (In the dev environment, it's localhost:3000 and 7007.) Any suggestions on how to resolve this issue?
