```
 final StandaloneResult<ThreeDS2Service, AuthenticationError> initialize(ThreeDS2ServiceConfiguration threeDS2ServiceConfiguration)
```
    Method to initialize the Standalone3DSService, passing the values from threeDS2ServiceConfiguration. The 3DS Requester App calls the initialize method at the start of the payment stage of a transaction. The app passes configParameters, UI configuration parameters, and (optionally) user locale to this method.
    Depending on the 3DS Requester App implementation, a ThreeDS2Service instance is called either during 3DS Requestor App startup as a background task or when a transaction is initiated. The state is maintained until the cleanup method is called.
    
    Parameters:
    
    threeDS2ServiceConfiguration - The ThreeDS2ServiceConfiguration parameters, including context, configParameters, locale, uiCustomization and challengeTimeout.
    
    Returns:
    
    instance of ThreeDS2Service on success and in failure it will return AuthenticationError
