React: Emoji, GIFs & Filters for Google Meet is a tool that lets you do interesting things during Google Meet or Hangouts video calls. For example, you can react to what other meeting participants are saying.

React is a Chrome extension that helps you get a feel of the conversations during a video call. The app works offline, so you can use it anytime, anywhere. 

How does the app work?

Once you install it, you will be asked to log in with your Google account.

When you are on a video call with a user, you will see a reaction toolbar in the top left of the screen. If you click the emoji or GIF buttons, you will be able to select a reaction.

You will be able to choose from one of the pre-defined reactions, such as "lol," "haha," or "good job."

When you are done selecting a reaction, you will see the reaction button will be displayed on your video stream.
