When a Dialogflow Agent is connected to Jumper, there might be cases where the ChatBot seems to give unsolicited responses which are not configure in Jumper (Automated Response, Bot Builder etc).
Most of the time these responses are from active Intents in the connected Agent. The most common example will be from [Default Welcome Intent]:
Unable to login to Dialogflow Agent
This usually happens when there are multiple gmail accounts available on your browser.
