How to use the calendar-utils.getMonthView function in calendar-utils

function getMonthView(events, viewDate, cellModifier, excluded) {

      // hack required to work with the calendar-utils api
      events.forEach(function(event) {
        var eventPeriod = getRecurringEventPeriod({
          start: moment(event.startsAt),
          end: moment(event.endsAt || event.startsAt)
        }, event.recursOn, moment(viewDate).startOf('month'));
        updateEventForCalendarUtils(event, eventPeriod);
      });

      var view = calendarUtils.getMonthView({
        events: events,
        viewDate: viewDate,
        excluded: excluded,
        weekStartsOn: moment().startOf('week').day()
      });

      view.days = view.days.map(function(day) {
        day.date = moment(day.date);
        day.label = day.date.date();
        day.badgeTotal = getBadgeTotal(day.events);
        if (!calendarConfig.displayAllMonthEvents && !day.inMonth) {
          day.events = [];
        }
        cellModifier({calendarCell: day});
        return day;
      });
