// Listen to all group conversations created by the specified sender
chat.onGroupConversationCreated(
  creatorAddress,
  (sender, conversationHash, conversationName, members) => {
    console.log(sender);
    console.log(conversationHash);
    console.log(conversationName);
    console.log(members);
  },
);

// Listen to all group conversations created by any sender
chat.onGroupConversationCreated(null, (sender, conversationHash, conversationName, members) => {
  console.log(sender);
  console.log(conversationHash);
  console.log(conversationName);
  console.log(members);
});
```

#### Stop watching

```ts
// Listen to all group conversations created by any sender
const stopWatching = chat.onGroupConversationCreated(
  null,
  (sender, conversationHash, conversationName, members) => {
    console.log(sender);
    console.log(conversationHash);
    console.log(conversationName);
    console.log(members);
  },
);

stopWatching();
```
