BetterTouchTool Notch Bar Item Placement

The Notch Bar is split into 4 parts. On the far left is a fixed area that doesn't scroll. Next comes a scrollable area that extends to the left edge of the notch, followed by another scrollable area right after the notch. At the far right there is again a fixed, non-scrollable area.

The fixed areas have higher priority. If you put many items into the fixed left or right area, the scrollable areas get smaller.

On standard screens you might not need both of the scrollable areas.
