When working with Voyager and Tabs

You can navigate from tab to tab like this: (Bottom Tab bar visible)

val navigator = LocalNavigator.currentOrThrow
navigator.push(NextTabScreen)

You can navigate to the regular screen from the tab ( Bottom Tab bar is not visible) 

val navigator = LocalNavigator.currentOrThrow
navigator.parent.push(NextRegularScreen("some message"))

This navigates to another regular screen that is implemented from the Screen.
