Google is finally rolling out emoji reactions to people using Google Meet for video calls starting today. The company said that this feature will be first available on iOS and the web with Android support coming soon. The search giant first announced this feature last year, but it is reaching users just now.

Users can click or tap on the smile icon on the bottom pane to post a reaction emoji — with support for different skin tones — on the video call. When users react with an emoji, you will see a small badge on the top-left corner of their tile on the web. If there are many people reacting at one time, you will see a stream of reactions on the left-hand side — just like comments on a live video.
