Cue IDs vs Chapters

What’s the difference between a cue identifier (similar to SRT)
https://w3c.github.io/webvtt/#introduction-other-features <https://w3c.github.io/webvtt/#introduction-other-features>

And a so-called “Chapter”?
https://w3c.github.io/webvtt/#introduction-chapters <https://w3c.github.io/webvtt/#introduction-chapters>
