difference between standalone Expo app and expo go

Question

I want to implement google sign in expo app. But while reading doc, it says expo-google-sign-in cannot be used in Expo Go. but it only works for standalone Expo apps https://docs.expo.dev/versions/latest/sdk/google-sign-in/#usage-with-firebase I don't understand what this means.

I have created expo app using expo init command. Is this standalone app or Expo go?

Please let me clear about this.

Wild guess here :

Expo Go is an app where you can test your app in it (when you scan the QR Code after expo start, your app is launched inside Expo Go app). Standalone Expo app is your application when you upload it on the store.

I had the same issue for notifications : inside Expo Go app, notifications didn't work for my app but when I uploaded my app on the AppStore, notifications worked fine.
