When a Workflow is triggered by an EventArc, can actions be taken on the "return" value?

Google Cloud Serverless Applications

For instance:

- complete:
        return: "complete"
    - failure:
        # TODO: Notify failure
        return: "failure"

Is there anything in the GCP toolset for me to send an email to DevOps on “failure”?
