It is vital to include these steps, as setting up the User Pool Domain correctly is crucial for enabling OAuth functionality. It ensures secure access to AWS resources and can influence the success of the entire sign-in flow.

Therefore, we kindly request the inclusion of the following in the AWS Amplify Flutter documentation:

- Explanation on the importance of the User Pool Domain in the OAuth process.
- Instructions on how to properly configure the User Pool Domain in the Authorized JavaScript origins for OAuth with Google Sign-In.
