Show toolbar on scroll up - CoordinatorLayout with multiple snapping points

Question

I am using this technique for creating multiple snapping points on collapsing toolbar (I use same layout and code)

But my question is how can I show the toolbar when user scrolls up at the middle of the recyclerview

Currently if user reaches the top, it shows the toolbar first, after that it expands collapsing toolbar

But I want to show the toolbar when user scrolls up at the middle of the recyclerview (before reaching top), after that, if user reaches the the top I want to expand collapsing layout.

How can I modify that answer for achive that?

Currently it looks like this. I want to show only the toolbar when user scrolls up if user reaches to top I want to show all collapsing toolbar

My AppBarLayout
