Unable to create custom hyperscript shorthands? (slate-hyperscript@0.100.0)

[beorn]

Using I don't seem to be able to create any custom elements (or HyperscriptShorthands). The documentation is "sparse" :) and the way I think it's supposed to work, the types seem broken:

import { createHyperscript } from "slate-hyperscript"

const h = createHyperscript({
  elements: {
    p: { type: "paragraph" },
    item: { type: "item" },
    text: {}
  }
})

h(
  "editor",
  {},
  h("cursor"),
  h("item", {}, h("p", {}, "p1")),
)

This results in the attached TS2345 error from TS for the h("item") and h("p") tags.

I think the tests have perhaps the best examples for using slate-hyperscript, e.g. https://github.com/ianstormtaylor/slate/blob/main/packages/slate/test/operations/set_node/remove-undefined.tsx
