Allow user switching between different groups if the user is in multiple groups

Environment information

NA

Describe the feature

Problem:
If a user is in multiple groups, currently there is not a way to specify the group during login so that the user can assume different roles.

Possible solution:
According to the Cognito documentation, the solution is to specify the CustomRoleARN parameter in the GetCredentialsForIdentity API call. Therefore the role ARN should be exported to the amplify_outputs.json file, and then the frontend amplify library should use this information to call the API.

Use case

Allow users switching between different groups.
