def send_task_heartbeat(taskToken=None):
    """
    Used by workers to report to the service that the task represented by the specified taskToken is still making progress. This action resets the Heartbeat clock. The Heartbeat threshold is specified in the state machine's Amazon States Language definition. This action does not in itself create an event in the execution history. However, if the task times out, the execution history will contain an ActivityTimedOut event.
