Like this:

// узнаем текущий активный объект (сразу выбран в меню табов)
const currentActiveObject = this.objectManager.clusters.state.get('activeObject');
// создаем монитор и следим за полем 'activeObject' 
this.activeObjectMonitor = new ymaps.Monitor(this.objectManager.clusters.state);
this.activeObjectMonitor.add('activeObject', (newActiveObject) => {
    console.log(newActiveObject);
}
