[CalendarView] Can't Blackout month or year items on calendarView component

[ToukZ]

Describe the bug

I am trying to make it so singular months and/or years are blackout on my WinUI3 application, but for now I haven't been able to.

For unique singular days, I was able to extract CalendarViewDayItem children from CalendarView and manage the IsBlackout property of them, but found out that there isn't any children named CalendarViewMonthYearItem for month or year objects.

I've tried to set the IsBlackout property of every day on a month and on a year to see if the component would smartly handle it by automatically setting that same property for months/years as true, but it doesn't seem to be the case.

After inspecting the application for more clarification of how the month objects are presented, I noticed that they are considered to be CalendarViewItem objects (See Screenshot 1).

Following that, I've tried to FindDescendants specifically for that type of child objects within a CalendarView component, but it doesn't seem to be a valid recognizable object to work with (See Screenshot 2).

Steps to reproduce the bug

1. Code a CalendarView component
2. Try to make blacked out months/years
   2.1. Try to set the IsBlackout property to true for all days in a month and/or in a year
   2.2. Try to modify the IsBlackout property on months and/or years
   2.3. Try to find CalendarView childs related to months and/or years
3. See error

Expected behavior

1. Months and Years should be instanciable objects that have a IsBlackout property that can be modified
   And/Or
2. Months and Years should automatically become blacked out if all days within that month/year have the property IsBlackout set to true.
