# onConversationRemoved

Sets up a listener for when a message is deleted from a conversation.

### Usage

```ts
const creatorAddress = '0x...';
const conversationHash = '0x...';

// Listen to all conversations removed by the specified sender
chat.onConversationRemoved(creatorAddress, null, (sender, conversationHash) => {
  console.log(sender);
  console.log(conversationHash);
});

// Listen to a specific conversation removed by any sender
chat.onConversationRemoved(null, conversationHash, (sender, conversationHash) => {
  console.log(sender);
  console.log(conversationHash);
});

// Listen to any conversation removal events
chat.onConversationRemoved(null, null, (sender, conversationHash) => {
  console.log(sender);
  console.log(conversationHash);
});
```

#### Stop watching

```ts
// Listen to any conversation removal events
const stopWatching = chat.onConversationRemoved(null, null, (sender, conversationHash) => {
  console.log(sender);
  console.log(conversationHash);
});

// ... Later, to stop watching for the events
stopWatching();
```
