How to use the queue.completed function in queue

function updateConfig(event, doc) {
			if (!doc) return;
			let config = configById(doc._id);

			if (doc.$set && doc.$set['queue.completed']) {
				Beeper.play();
				Notify.info({
					message: `Run of ${config.name} completed`,
					url: `#/config/run/${doc._id}/list`,
					target: '_self'
				}, {
					allow_dismiss: true, delay: 30000
				});
			}

			ConfigListResource.get({id: doc._id}).$promise.then(function(data) {
				config.name = data.name;
				config.queue = data.queue;
				config.type = data.type;
				config.archived = data.archived;
				updateState(config);
