Samsung - How to get Windows Phone nav bar?

Hello,

I tried a nav bar app, its cool but its partially cutting off stuff from screen since its just on top of apps, not sure how to make it same size as the default nav bar.

Also, when in landscape, the other side will have default and otherside has the windows navbar.

Anyway to fix? Also, it affects keyboard in numpad when typing like outlook pin, kindly assist.

Also, can we discuss on Discord or tele? Thanks.
