Coverflow effect not working

Hi, I have upgraded the angular2-useful-swiper to 8.1 version and now it seems like coverflow effect is not working. In last version, document says we should manually add swiper.js to index.html or angular.json.

Is that causing the issue? Below added my configuration:

public dialerConfig: SwiperOptions = {
    effect: 'coverflow',
    grabCursor: true,
    centeredSlides: true,
    initialSlide: 5
    slideToClickedSlide: true,
    simulateTouch: true,
    keyboard: true,
    preventClicks: false,
    hashNavigation: true,
    coverflowEffect: {
      rotate: 0,
      stretch: 0,
      depth: 100,
      modifier: 6,
      slideShadows: true
    },
    slidesPerView: 'auto'
  };

Also some events seems to be changed/updated. Earlier I was able to call the transitionStart, but now it seems to be changed. Any alternatives?

onTransitionStart: (swiper) => {
      this.pageChange(swiper.activeIndex);
    }

Thanks in advance
