How to add custom area inside Shell with custom content?

[SergTomcat]

I need to modify Shell to create a custom area that persists through navigation (like toolbar or tabbar) and doesn't require modifying and controlling every page, that I can show/hide upon necessity. Is there a way to implement it?

I don't even need it to be MAUI content area, I can create content for Android/iOS with Android.View/UIView.
