Event for when groups change?

[realwakils]

I would like to know how I can know when the groups change? For example when I change one of my devices into another group.

I tried with ZoneTopology but the event was never called

Node version: v14.15.2 node-sonos version: the latest OS: windows 10

import { Listener } from 'sonos';

Listener.on('ZonesChanged', (...args) =>{});
