如何让Bootstrap popovers在FullCalendar 4中工作？

var calendar = new FullCalendar.Calendar(calendarEl, {
  // FullCalendar的配置选项
});

var events = [
  {
    title: 'Event 1',
    start: '2022-01-01',
    popoverContent: '<strong>Event 1</strong><br>Popover content for Event 1'
  },
  {
    title: 'Event 2',
    start: '2022-01-02',
    popoverContent: function() {
      return '<strong>Event 2</strong><br>Popover content for Event 2';
    }
  }
];

var calendar = new FullCalendar.Calendar(calendarEl, {
  // FullCalendar的配置选项

  eventRender: function(info) {
    $(info.el).popover({
      title: info.event.title,
      content: info.event.extendedProps.popoverContent,
      trigger: 'hover',
      placement: 'top',
      container: 'body'
    });
  }
});

calendar.render();
