Click on the Find people, rooms, bots search box, then Find a bot and search for “Clever Ads”.
In order to start using the bot on Google Chat you will first have to login with an email that is associated at least to an advertiser’s account.
Once you have logged in successfully you can access your dashboard, configure your preferences, schedule your reports, etc. Don’t forget that you can also ask your Google Chat Bot directly for metrics & graphs.
