title: Create a chatbot using Dialogflow and it doesn't work in group or space
body: <p>I created a chatbot by using dialogflow and integrated it with google chat. When I talk to it in a DM, it works. But when I add it to a group or space, the bot wont response to my question. Is there some setting I'm missing? I would be very grateful for any suggestions.
