None are selected since you may not be in that destination exactly.
So you either want to hide the bottom bar, or check the backstack, and see if any of the parent destinations are one of those destinations that make the bottom bar light up, and if that’s the case pick that bottom bar item to be highlighted.
With that said, how do you currently select which item will be highlighted in the bottom bar? By looking at that it may be easy to suggest something

Copy code
navBackStackEntry?.destination?.hierarchy?.any {
it.route == item.getRoute()
} == trues
