How to use the hydrosdk.sdk.Application function in hydrosdk

def main(model_name, model_version, application_name, hydrosphere_uri, *args, **kwargs):
    logger.info(f"Referencing existing model `{model_name}:{model_version}`")
    model = sdk.Model.from_existing(model_name, model_version)
    logger.info(f"Creating singular application `{application_name}`")
    application = sdk.Application.singular(application_name, model)
    logger.info(f"Applying application to the cluster `{hydrosphere_uri}`")
    result = application.apply(hydrosphere_uri)
    logger.info(pprint.pformat(result))
