These two are equivalent (I believe):

    @ViewChildren(RoundedContainerComponent) roundedContainers!: QueryList<RoundedContainerComponent>;
    private rounded = toObservable(contentChildren(RoundedContainerComponent))

I can call the Query List for changes

this.roundedContainers.changes
  .pipe(
    takeUntilDestroyed(this.destroyRef),
  )
  .subscribe(t => {
  this.scrollToContainer('-86.0px')
})

How can I do the same for this.rounded (which should be an observable). ‘changes’ is not accessible, only pipe and subscribe.

This doesn’t work on initialisation

this.rounded
  .pipe(
    takeUntilDestroyed(this.destroyRef),
  )
  .subscribe(t => {
    this.scrollToContainer('-86.0px')
  })
