Email not saving in Meeting Participants Report

Using Web Client SDK 2.3.0

When passing in an email in the ZoomMtg.join() method, it does not show up in my reports after the meeting.

Also, where can I see customerKey in the reports?

    ZoomMtg.join({
        meetingNumber: meetingNumber,
        userName: userName,
        userEmail: userEmail,
        passWord: password,
        customerKey: 'gthr',
        apiKey: apiKey,
        signature: signature,
        success: function(res){
            parent.postMessage({
                type:"event.joinSuccess"
            },"*");
        },
        error: function(res){
            console.log("Join Meeting Error: ", res);
        }
    });
