WorkflowTarget

An EZGH Workflows workflow in the queue's project: each message starts a run, its input the message ({messageId, body, attributes, sentAt, queueId, groupId?, seq?}); the message is acknowledged once the start is accepted, and a redelivered message reaches the run its first delivery started. One message per call (batchSize 1); on a FIFO queue a group's next message waits for the previous start. Configuring it needs queues.subscriptions.create (or update) and workflows.runs.start (resume: workflows.runs.resume) on the workflow (<app's resourceName>/). No signing secret.
