Extensions add powerful features to your chat app without writing any code. Simply enable them in your CometChat Dashboard, and they automatically appear in the UI Kit components.

How Extensions Work

1. Log in to your CometChat Dashboard
2. Navigate to the Extensions section
3. Enable the extensions you want
