## Overview

`CometChatCallBubble` renders a direct-call / meeting message — a call icon, a title, a timestamp subtitle, and a **Join** button. It is **self-extracting**: pass the SDK `message` and the bubble derives the call type, session ID, title, icon, and timestamp itself, so it works standalone. Use `onJoinClick` to start the call when the user taps Join.
