How to use the @better-scroll/core.use function in @better-scroll/core

BScroll.use(MouseWheel)

      options.mouseWheel = {
        speed: wheelDistance,
        invert: false,
        easeTime: 300
      }
    }

    if (!mouse) {
      options.click = false
      options.disableMouse = true
    }

    if (getType(pullup) === 'function') {
      BScroll.use(Pullup)

      const wrapper = temp.cloneNode()
      wrapper.classList.add('pullup-wrapper')

      const tip = spanTemp.cloneNode()
      tip.textContent = pullupTip || 'Loading...'

      wrapper.appendChild(tip)
      tbody.appendChild(wrapper)

      this.pullupWrapper = wrapper

      options.pullUpLoad = {
        threshold: parseInt(pullupThreshold) || 10
      }
    }
