Moderators can create polls that remain viewable only to other mods until they decide to launch them. When a poll is closed, moderators receive the results, which they can share with participants. At the end of the meeting, hosts are automatically sent poll results.
The new features are being released via gradual rollout that starts on October 8th, meaning it could take up to two weeks for the features to show up. Q&A and Polls will only be available to those with paid accounts, such as G Suite Essentials, G Suite Business, G Suite Enterprise and G Suite Enterprise for Education.
