When the event is on Teams, Zoom or another platform

Watch on the other platform and take part on the event page.

Some events stream on another service, such as Microsoft Teams, Zoom, Webex, Google Meet, YouTube, Vimeo, LinkedIn, Facebook, GoTo Webinar or ON24. You watch the video there, but you ask questions, answer polls and vote on the event page.

Steps

Open the event page. Instead of the video, it says "This event is streaming on Microsoft Teams", or whichever service is used.
Choose Open in Microsoft Teams (or the name of the service), or Open the stream. It opens in a new tab.
Keep the event page open in another tab. Go back to it to ask questions, answer polls and vote.
