You are exactly right here, if you want to hide the scrollbar when scrolling.
- Create a screen
- Add a vertical arrangement
- Set the height to “fill parent” and the width to 97 percent
- Drag a new vertical scroll arrangment in the vertical arrangement
- Set the height from the vertical scroll arangment to “fill parent” and the width to 100 percent
- Now the scrollbar is no longer visible when scrolling
