Problem with UltimateExpress bindings

I might have misunderstood, but couldn’t you do this instead:

module Router = {
  type t
  @module("ultimate-express") @scope("default")
  external make: unit => t = "Router"
}

When used, it generates:

import * as UltimateExpress from "ultimate-express";

let router = UltimateExpress.default.Router();

Which should work as expected.
