How to Implement Replace behaviour like fragment transactions with navigator?

@Tlaster
This approach is not working

navigator.popBackstack()
navigator.navigate( route )

Little debugging showed me this method updated the value of canNavigate
destroyDirectly() requestNavigationLock.invoke(false) // this was called, which restricted naivigation

Can we do something with navOptions?

A, B, C, D

My use case
A(bstack), B(bstack) -> C -> (replace with D on navigation)

You can use with NavOption's popUpTo

@Tlaster Thanks!
But It does not help in my case since popUpTo clears all the backstack entries. I want to keep A and B in backstack and replace C with D.
So if i am at C screen what should i write to replace C with D. From D onBackpress B -> onBackPress -> A

No, popUpTo does not clear all backstacks, here is an working example you can try:

NavHost(
    navigator = navigator,
    initialRoute = "/a",
) {
    scene("/a") {
        Column {
            Text("A")
            Button(onClick = {
                navigator.navigate("/b")
            }) {
                Text("Go to B")
            }
        }
    }
    scene("/b") {
        Column {
            Text("B")
            Button(onClick = {
                navigator.navigate("/c")
            }) {
                Text("Go to C")
            }
            Button(onClick = {
                navigator.goBack()
            }) {
                Text("Goback")
            }
        }
    }
    scene("/c") {
        Column {
            Text("C")
            Button(onClick = {
                navigator.navigate(
                    "/d",
                    options = NavOptions(popUpTo = PopUpTo("/c", inclusive = true))
                )
            }) {
                Text("Go to D")
            }
        }
    }
    scene("/d") {
        Column {
            Text("D")
            Button(onClick = {
                navigator.goBack()
            }) {
                Text("Goback")
            }
        }
    }
}
