I want to implement a workflow in an actor: 1.verify user permission (rest call to authentication service) 2. Verify if transaction can be done (call to another service) 3. Write transaction to database 4. Send purchase orders to warehouse 5. Create purchase confirmation. Ideally I want to do this via 5 lines with async. I will receive the client order in the actor and then start The workflow. I know that async is not allowed inside the actor. But is it possible to span of a task to run this workflow?
