Are you new to Dialogflow?
Don't waste your time asking questions on the forums for simple features. In my "10 must know features" webinar, you will learn about some important Dialogflow features which will speed up your bot development workflow (or improve your bot in some other ways).
I have written about Must Know features of Dialogflow before, and this webinar is updated for 2019.
