How to add animation for vertical trays

Hey,
I want to add custom animation when scroll top to bottom and bottom to top mean for vertical trays.

Please help for this.

The issue does not name a sample, file, entry point, or test. First locate the Android TV sample that contains the vertical trays and document its current scroll behavior; the request needs a defined animation scope and acceptance criteria before implementation can be considered done.
