How to incorporate existing type?

I have a type imported from a third-party API and I'd like to build it in into my ark type:

import { Foo } from 'fancy-api'

const schema = type({
  foo: // how to put Foo here?
})

import { Foo } from 'fancy-api'

const schema = type({
  foo: // how to put Foo here?
})
