+
+When a channel is deleted, an event is shared from the backend which could be listened to get the status of the deleted channel.
+Users can listen to the event and store the status of the deleted channel and thereby display the appropriate messa
+
+```tsx
+client.on('channel.deleted', (event) => {
+  if (event.cid === channel.cid) {
+    // add your action here
+  }
+}),
+```
