How can you mute notifications for a specific chat in WhatsApp?

To mute notifications for a specific chat in WhatsApp, you can follow these steps:

1. **Open WhatsApp**: Launch the WhatsApp application on your smartphone.

2. **Open Chat**: Navigate to the chat for which you want to mute notifications.

3. **Access Chat Settings**: On Android, tap on the three vertical dots in the top-right corner of the chat screen and select "View contact" or "Group info." On iOS, tap on the contact or group name at the top of the chat.

4. **Mute Notifications**:

   - **Android**: Tap on "Mute notifications" and select the duration you want to mute notifications for (8 hours, 1 week, or 1 year). Confirm your selection.
   
   - **iOS**: Scroll down in the chat info screen and tap on "Mute" under "Notifications." Select the duration you want to mute notifications for (8 hours, 1 week, or 1 year). Confirm your selection.

5. **Confirmation**: Once muted, you will see a mute icon (a crossed-out speaker) next to the chat name or in the chat settings, indicating that notifications for this chat are muted.

By muting notifications for a specific chat, you won't receive sound or vibration alerts when new messages are received in that chat, although you will still see the messages when you open WhatsApp.
