  3. sealed trait Envelope extends Message

    A Proto event with additional attributes and claims.

    A Proto event with additional attributes and claims. To pattern match on an Envelope use the Event.unapply or Request.unapply extractors.

    val behavior: Behavior[Envelope] = Behaviors.receiveMessagePartial {
  case Event(SomeEvent(eventData)) => ???
  case Request(scope, SomeCommand(eventData)) => ???
