How to add Q&A to a Microsoft Teams meeting?

The Q&A app in Microsoft Teams meetings allows meeting organisers and presenters to add moderated Q&A capabilities to any Teams meeting.
You can choose open or moderated Q&A, mark the best answer for a question, filter responses, enable replies and more.
Q&A in Teams meetings is ideally suited for large and more structured meetings, such as leadership presentations, webinars, training sessions, general meetings and community events.
Designated presenters can act as co-moderators to screen questions. The Q&A app will be generally available in September.

The Q&A app doesn't even show up as an option for me under the +. I'm on a Mac. I doubt that matters, but perhaps? Any help?
Hi Brad! It could be possible that the app is not yet there. I'm sure in the next weeks/months there will come clarification on this.
