SfCalendar special dates background customization in MAUI

Question

In my maui application I'm using sfcalendar and adding few special dates on that calendar. Currently am able to set bg color and text style for the special dates . But I want to show the special dates in the calendar inside a circle, like the below image.

But my code is not working like the above image. Current UI and code.

`  calendarcontrol.MonthView = new CalendarMonthView()
        {
            SpecialDayPredicate = (date) =>
            {
                if (SpecialDateLists.Any())
                {
                    foreach (var item in SpecialDateLists)
                    {
                        if (item.Date == date.Date)
                        {
                            CalendarIconDetails calendarIconDetails = new CalendarIconDetails();
                            calendarIconDetails.Icon = CalendarIcon.Square;
                            calendarIconDetails.Fill = Color.FromArgb("#72a951");
                            return calendarIconDetails;
                        }
                    }
                }
                return null;
            },
            SpecialDatesBackground = Color.FromArgb("#EAEDED"),
          
        };
