How do I enable_logging for ModelMonitoringAlertConfig in GCP?

I am trying to enable_logging in ModelMonitoringAlertConfig I have tried:

from google.cloud import aiplatform_v1 as vertex_ai_beta
...
    alerting_config = vertex_ai_beta.ModelMonitoringAlertConfig(
    enable_logging=True,
    email_alert_config=vertex_ai_beta.ModelMonitoringAlertConfig.EmailAlertConfig(
        user_emails=NOTIFY_EMAILS
    )
)

gives:

 Unknown field for ModelMonitoringAlertConfig: enable_logging

but this suggests it should work. What am I missing?

(I have also tried aiplatform_v1beta1.)
