How do you set data retention policy on IoT Sitewise time series store?

Going off this suggested architecture. https://pages.awscloud.com/Building-an-End-to-End-Industrial-IoT-IIoT-Solution-with-AWS-IoT_2020_0216-IOT_OD.html

The suggested architecture for industrial IoT applications is IoT SiteWise for operational "hot" data store and IoT Analytics -> S3 for the "warm/cold" data lake. IoT Analytics allows you to set the data retention policy on its data stores. We don't want the "hot" data store to contain historical data when IoT Analytics -> S3 already handles that for us. Also, we want to avoid siloing data between SiteWise and IoT Analytics. Is there a way to set the data retention policy on IoT SiteWise?

I've already looked through the documentation for SiteWise, not sure if I missed something.
