Mixpanel Anomaly Detection: Seasonality Support with Prophet?

Hello. I am taking a look at the Mixpanel Anomaly Detection feature. The doc references the use of Prophet the open source anomaly detection library. Prophet supports the concept of seasonality, but I don't see any controls in Mixpanel Custom Alerts to leverage seasonality. My company is unable to utilize the anomaly detection due to the high seasonality of our events. Is there a way to utilize the seasonality functionality that Prophet supports that I am missing, or is it not supported at all?
