Ссылка на LazyColumn возвращает начальное положение

У меня есть приложение. Большая картинка и снизу идет LazyColumn. Когда я перехожу по 4 (или 5) ссылке и потом назад мой LazyColumn оказывается в начальном положении. Ссылка 1 в самом верху. И когда я хочу снова ссылку 4 мне приходится "крутить".

Кнопка "Назад" на "родной" навигационной панели другая. Когда я возвращаюсь назад LazyColumn уже ждет меня в том виде, в котором я ее оставила.

Что нужно сделать в программе что бы и верхняя кнопка вела себя так-же как и кнопка "назад" на навигационной панели?

Вот мои файлы:
