Set to token to specify that the client should get the access token (and, optionally, ID token, based on scopes) directly.

WriteAttributes

The user pool attributes that the app client can write to.

If your app client lacks write access to a mapped attribute, Amazon Cognito throws an error when it attempts to update the attribute. For more information, see Specifying Identity Provider Attribute Mappings for Your User Pool.
