Figure outline customization (number+caption) in Typst 0.13

Update: I figured it out myself. It’s it.prefix().children.at(2).

The final code thus becomes:

  // Make the Lists of Figures/Tables/... more concise and easier to read, like in the LaTeX templates
  show outline.entry: it => context {
    if it.element.has("kind") {
      let loc = it.element.location()

      if counter(figure.where(kind: it.element.kind)).at(loc).first() == 1 {
        v(1em)
      }

      show link: set text(rgb("000000"))
      block(
        link(loc,
          box(it.prefix().children.at(2), width: 2.6em)  // figure number
          + it.body()                     // figure caption
          + box(it.fill, width: 1fr)
          + it.page()
        )
      )
    } else {
      it
    }
  }
