Publish. Once the Listing, Theme & Assets, and Targeting have been defined, select STREAMS from the top menu and then select PUBLISH.
Streams do not need to be re-published when you make changes. Any new episodes that you add will be auto-published. Subscribed users will be notified.
Publish to Pathway only
When you create content in Streams you can choose to Publish to Pathway Only. This means that the content will not be published to the app as stand-alone content, but can only be accessed in a Pathway.
