Can I somehow detect when Angular cdk overlay changes it's position?

When I did this, I was able to access the change from the overlay reference config. It looked something like this:

export class MyClass {
  constructor(private overlayRef: OverlayRef) {}

  ngOnInit() {
    const config = this.overlayRef.getConfig();
    // positionChanges is private so this bypasses the error
    const changes = (config.positionStrategy as any)['positionChanges']

    changes.subscribe((change: ConnectedOverlayPositionChange) => {
      // Do something when the position changes
    });
  }
}
