Как использовать ViewPager2 с макетом CollapsibleToolbar

Я пытаюсь чего-то добиться с макетом collapsible toolbar, и у меня есть 2 вкладки с viewPager2

Ниже приведены два изображения, например, для случая расширенный снимок экрана и свернутый скриншот.

Ниже приведен код, который у меня есть в XML, и я не уверен, где он идет не так... в этом случае моя прокрутка не работает должным образом. Я хочу, чтобы панель инструментов оставалась сверху, когда она свернута

Я пытался добавить toolbar внутрь AppbarLayout, но это не сработало.

Также пробовал ниже ссылки у меня почему-то не работает Ссылка1Ссылка2
