How to use `customer_key` in meeting participants report?

It is not working. Customer_key value is always blank in the response. I think this is the same issue we are facing with userName and userEmail. @tommy suggested me to use “customerKey” property here:

Here is my code. Please suggest what should we do?

ZoomMtg.preLoadWasm();
ZoomMtg.prepareJssdk();

$(function() {
    ZoomMtg.init({
    leaveUrl: 'http://myhomepage.com',
    isSupportAV: true,
    disableInvite: true,
    disableCallOut: true,
    audioPanelAlwaysOpen: true,
    meetingInfo: [],
    success: function() {
		ZoomMtg.join(
		{
    			meetingNumber: '83523******',
    			passWord: '******',
    			userName: 'Harshal',
    			participantId: 'id****',
    			customerKey : 'id****',
   		 	 userEmail: 'user***@myhomepage.com',
    			signature: '****',
    			apiKey: '***',
    			success: function(res) {
       				ZoomMtg.showInviteFunction({
           				show: false
       				});
       				ZoomMtg.showRecordFunction({
          				show: false
       				});

       				setTimeout(function() {
          				var startButton = document.getElementById('pc-join');
          				if (startButton != null && startButton !== undefined)
          				{
              					startButton.click();
          				}
       				}, 1500);

      				$('.meeting-info-icon__icon').remove();
   			},
  			error: function(res) {
    				console.log(res);
  			}
  		});
  	},
	error: function(res) {
 		console.log(res);
	}
    });
});

Participant API is returning customer_key blank:
