DialogflowCX - escalate conversation after 30 seconds of no user input

[dianabisbe]

Hello, 

At point of the conversation, after we´ve prompt the user to imput a comment, we need to escalate the conversation if the user takes longer that 30 seconds to respond. Our way of escalating the conversation is to send a parameter to the sessionInfo.

Is there a way to implement a timer to pass the parameter to sessionInfo if there hasn´t been any response from the user, 30 seconds after our last message? (Without using the Dialogflow CX API)

Thank you!
