Is it possible to Remove EventSources and add them back dynamically based on View Name?

问题

I'm trying to set up a calendar with multiple views that are all identical except for the events displayed on each. I am able to remove EventSources by ID through the viewSkeleton Render callback - but I am unable to add an EventSource back to the calendar.

Searched extensively for ways to toggle visibility and things like that - but most results are for previous versions of FullCalendar - trying to accomplish this in v4.

Reduced Test Case: https://codepen.io/jacobcboe/pen/MReJep

I'm actually trying to do this with Google Calendar EventSources, but used array events for test case for simplicity.

document.addEventListener('DOMContentLoaded', function() {
  var calendarEl = document.getElementById('calendar');

  var calendar = new FullCalendar.Calendar(calendarEl, {
    plugins: [ 'timeGrid' ],
    views: {
	    view1: {
			type: 'timeGrid',
			duration: { days:7 },
			buttonText: 'view1'
		},
		view2: {
			type: 'timeGrid',
			duration: { days:7 },
			buttonText: 'view2'
		},
		view3: {
		    type: 'timeGrid',
			duration: { days:7 },
			buttonText: 'view3'
		},
		view4: {
			type: 'timeGrid',
			duration: { days:7 },
			buttonText: 'view4'
		}			
	},
    defaultView: 'view1',
    defaultDate: '2019-04-05',
    header: {
      left: 'view1,view2,view3,view4',
      center: '',
      right: ''
    },
    eventSources: [
      {
        id:'1',
        events: [
        {
          title: 'All Day Event',
          start: '2019-04-05'
        },
        {
          title: 'Long Event',
          start: '2019-04-06',
          end: '2019-04-07'
        }]
      },
      {
        id:'2',
        events:[
          {
            groupId: '999',
            title: 'Repeating Event',
            start: '2019-04-05T16:00:00'

          {

          }]
      },
      {
        id:'3',
        events: [
          {
        title: 'Meeting',

      eventSourceTwo.remove();

      eventSourceThree.remove();
      //also tried calendar.getEvents() with remove
      var viewName = info.view
      if(viewName.type =='view1'){

  calendar.render();
