With reactions, you can send on-screen emojis to express your reactions to what is going on without interrupting the flow of the meeting.
You can send these reactions: smile, sad, wow, haha, celebrate, clapping hands, thumbs up, and thumbs down.
When you send a reaction, it's visible to you and all other participants in the meeting. The reactions are displayed anonymously. The incoming reactions are displayed as a stream of emojis on the right side of the screen.
The host and cohost in a meeting can enable and disable the reactions from the participant list. Go the participant list, tap the More (...) button, and toggle the Reactions in meeting on or off.
Use Reactions in a Meeting
If reactions are available in a meeting, you can see a React button in the call control menu on your touch controller or the integrated touch screen. Tap React and select the emoji you want to send.
If you don't see the React button, the reactions may be found in the More menu in the call controls.
