FullCalendar: borderColor/backgroundColor not working for month view

In Fullcalendar, I have used eventDataTransform to set borderColor & backgroundColor. For Month view event's borderColor & backgroundColor is not taking effect.

i am expecting to take borderColor/backgroundColor effect for month view.

Current event object:

events = [{
    title: 'Timed Event',
    start: '2020-06-23T16:00:00+00:00',
    borderColor: 'red',
    backgroundColor: 'green'
}]

Please suggest some solution for the issue.

If we use event's display property to "block", then it sets the backgroundColor and borderColor of the event for all views, including month view.

Example:

events = [{
    title: 'Timed Event',
    start: '2020-06-23T16:00:00+00:00',
    display: 'block',
    borderColor: 'red',
    backgroundColor: 'green'
}]
