Auto refresh with Amazon Timestream

I am looking to setup live analytics with Amazon Timestream using Quicksight. As per the documentation, autorefresh is available for Amazon Timestream and Amazon Opensearch. However, while publishing the dashboard option for enabling auto-refresh is available for Opensearch(as shown in the blog below) and don’t see the same one with Timestream. Anyone worked on or faced this before?

Autorefresh functionality is only available for Session Capacity Based Subscriptions and is a preview feature that needs to be requested for whitelisting.
