How to use the @better-scroll/shared-utils.Probe.Throttle function in @better-scroll/shared-utils

private dispatchScroll(timestamp: number) {
    // dispatch scroll in interval time
    if (timestamp - this.startTime > this.options.momentumLimitTime) {
      // refresh time and starting position to initiate a momentum
      this.startTime = timestamp
      this.scrollBehaviorX.updateStartPos()
      this.scrollBehaviorY.updateStartPos()
      if (this.options.probeType === Probe.Throttle) {
        this.hooks.trigger(this.hooks.eventTypes.scroll, this.getCurrentPos())
      }
    }

    // dispatch scroll all the time
    if (this.options.probeType > Probe.Throttle) {
      this.hooks.trigger(this.hooks.eventTypes.scroll, this.getCurrentPos())
    }
  }

private dispatchScroll(timestamp: number) {
