BottomNavigationView отображается не во всех фрагментах [closed]

От: Из: Общие

У меня вопрос, код kotlin ниже определяет, что BottomNavigationView виден только в activity_main, а не во фрагментах, присутствующих в нижней части навигации, суть в том, что нижняя панель видна только на первой странице, а не в остальных фрагментах, что это из-за? что мне нужно сделать, чтобы меню отображалось во всех пользовательских интерфейсах

        when (it.itemId) {
