Current regional availability of Redshift Streaming Ingestion for Kinesis Data Streams Beta?

I'm interested in the recently announced Beta feature for Redshift: Streaming Ingestion for Kinesis Data Streams https://aws.amazon.com/about-aws/whats-new/2022/02/amazon-redshift-public-preview-streaming-ingestion-kinesis-data-streams/ because it simplifies the setup enabling one to skip the S3 intermediary step.

The news article links to the regional product overview https://aws.amazon.com/about-aws/global-infrastructure/regional-product-services/ which does not list this specific beta program. I've tried different regions, but can't find it anywhere.

Can somebody (from AWS?) list the regions where this feature is currently available in beta? Or better yet, update the regional page to make it more explicit on this feature?
