Events

Run your code when the unread count changes.

Iris.on("unread", (count: number) => void): void

unread

The listener runs once with the current count, then on every change. Use it to show a badge on your own button when the launcher is hidden.

const badge = document.querySelector("#help-badge");

Iris.on("unread", (count) => {
  badge.textContent = String(count);
  badge.hidden = !count;
});
