   "automatedAgentReply": { # Represents a response from an automated agent. # Only set if a Dialogflow automated agent has responded. Note that: AutomatedAgentReply.detect_intent_response.output_audio and AutomatedAgentReply.detect_intent_response.output_audio_config are always empty, use reply_audio instead.
+    "allowCancellation": True or False, # Indicates whether the partial automated agent reply is interruptible when a later reply message arrives. e.g. if the agent specified some music as partial response, it can be cancelled.
+    "automatedAgentReplyType": "A String", # AutomatedAgentReply type.
     "detectIntentResponse": { # The message returned from the DetectIntent method. # Response of the Dialogflow Sessions.DetectIntent call.
       "outputAudio": "A String", # The audio data bytes encoded as specified in the request. Note: The output audio is generated based on the values of default platform text responses found in the `query_result.fulfillment_messages` field. If multiple default text responses exist, they will be concatenated when generating audio. If no default platform text responses exist, the generated audio content will be empty. In some scenarios, multiple output audio fields may be present in the response structure. In these cases, only the top-most-level audio output has content.
       "outputAudioConfig": { # Instructs the speech synthesizer on how to generate the output audio content. If this audio config is supplied in a request, it overrides all existing text-to-speech settings applied to the agent. # The config used by the speech synthesizer to generate the output audio.
