To be honest no - I only do paid consults. Def not trying to be rude at all. If you have Google connected you need to add the scopes to be used and saved to that user. So when they click tools and connect to calendar and the assistant will automatically call it. Of course you need the tool built as well and pass the oAuth creds for it to work. I honestly would not suggest building it with voice (just have the user click a button an connect it). Yea that's super cool, but do have have at least a button working before you try to do speech commands?
