`ChatManager#fetch(): Promise` `ChatManager#fetch(options: ChatFetchOptions): Promise` Fetches chats from the API. The `options` parameter can be used to specify pagination. Usage: ```js client.chats.fetch() ```

`ClientMember#setNickname(nickname: string): Promise` Changes the client member's nickname in the group. Usage: ```js const group = client.groups.cache.get('12345') group.me.setNickname('Pete') ```

`Group#add(id): Promise` `Group#add(ids: []): Promise` Add a user (or users) to a group. Usage: ```js const group = client.groups.cache.get('12345') group.add('67890') group.add(['67890', '24680']) ```

`FormerGroup#rejoin(): Promise` Rejoins a group that had previously been left. Usage: ```js const formerGroup = client.groups.former.cache.get('12345') formerGroup.rejoin() ```
