No function disconnect()

[sgmv]

I have a problem with missed functionality - disconnect from rabbit cluster. I want graceful disconnect from my cluster and can't find this ability. If I use the close() method from AmqpConnectionManager, it's just close channel, but don't disconnect from a cluster.
Here object after close method:

AmqpConnectionManager { _events: [Object: null prototype] {}, _eventsCount: 0, _maxListeners: 0, _channels: [], _currentUrl: 1, connectionOptions: undefined, heartbeatIntervalInSeconds: 1, reconnectTimeInSeconds: 1, _findServers: [Function], _connecting: true, _closed: true, _urls: [ 'amqp://user:[email protected]:5672?heartbeat=60' ], _currentConnection: null }
As you see, connecting is true.
