OutgoingCall
class OutgoingCall @InternalWowApi constructor(val type: String, val command: Command<*>, val wait: WaitContext? = null)
One synchronous call to another context's command gateway: command, of the full type name type (context.aggregate.Command), with the wait context a wait that follows the calling saga goes on with, or null. The command carries the root command's scope, operator and causation, which the client asserts on the target's internal port, naming its service.
