4. **Record Your Audio Message:**
- While holding the microphone icon, speak your message into the iPhone's microphone.
- You can lift your finger to stop recording or swipe to the right to cancel the message.
5. **Send the Audio Message:**
- After recording your message, you'll see a play button to listen to it.
