Place it just before the reply text becomes visible, then follow it with a Discord notification when several chats arrive together, so the exchange reads as a rapid back-and-forth. A soft bell ding afterwards can mark the conversation ending without breaking the flow.

This is a brief electronic notification from WhatsApp Web, lasting just over two seconds, with a clean two-note chime that signals an incoming message. It feels instantly familiar and mildly urgent, like glancing at a phone during a quiet moment and realising someone has replied. The cue comes from the browser version of the messaging service, where it marks new activity in an online conversation.
