One of the best current demos of Flow Orchestration is this Incident Management recording.
You can now spin up a new org that contains the full implementation of this orchestration, allowing you to examine the different parts of the configuration. All you need to provide to create this org is your email address. The resulting scratch org will last for 30 days.
Once the org is created, you can use the same link to return to the org’s Launch button.
Inside the org, go to Setup–> Flow to explore the parts of the orchestration.
