I use lib in one place:

 <ng-container *async="let config; from: config$;">

'config$' var is:

 this.config$ = this.store.pipe(
      select(fromDynamicList.getDynamicListConfig),
      filter(config => !!config),
      tap(config => {
        this.setFabButtonItems(config.route, config.name);
      })
    );
