private static client = new CognitoIdentityProviderClient({ region: 'us-east-1' });

• InitiateAuthCommand is used in the refreshTokensIfNeeded method but is not imported. Please add the appropriate import statement for InitiateAuthCommand from the AWS SDK.

const refreshCommand = new InitiateAuthCommand(refreshParams);
