In Tree component, the elements prop is mainly for internal logic — it’s not used for rendering the UI directly.

It helps with things like:

• Expanding the right folders when a selectedId is passed (expandSpecificTargetedElements function).
• Auto-expanding parent folders when a file or folder is selected.
• Supporting the CollapseButton (expand/collapse all) by keeping track of the full structure.

The actual UI is rendered manually by writing <Folder> and <File> components inside the .
