[Question] Why doesn’t WWOTF mention the Bronze Age Collapse?

One of the major criticisms of Kurzgesagt’s video on civ collapse (which is based on WWOTF) is that it didn’t mention the Bronze Age Collapse, which was a widespread, monumental civilizational collapse that “regressed scientific and technological development.” Reading through chapter 6 of WWOTF (“Collapse”) right now, I’m dismayed that it doesn’t mention the Bronze Age Collapse either. Although Will writes that “all historical civilisational collapses to date have been local” (p. 157), the Bronze Age Collapse seems like an exception because it spanned much of the Mediterranean region. Is this an oversight on Will’s part or was there a reason why he didn’t include it in the book (including lack of space)?
