Hello there, Currently

service.kt [Snippet 1]

@file:JsExports

external interface ServiceConfiguration {
  var appId: String
  var debug: Boolean?
}

fun service(config: ServiceConfiguration)

Yields the following typescript declaration (code out of this context is redacted): [Snippet 2]

type Nullable<T> = T | undefined | null

export interface ServiceConfiguration {
  appId: string;
  debug: Nullable<boolean> // want this to be optionally provided
}

export function service(config: ServiceConfiguration);

After importing this bundled library in typescript, calling [Snippet 3]

const service = service({ appId: "<app-id>" }) // troubles the ts compiler

The compiler expects both arguments like so [Snippet 4]

const service1 = service({ appId: "<app-id>", debug: undefined }) // ts compiler is happy
const service2 = service({ appId: "<app-id>", debug: true }) // ts compiler still happy

Question is, how do I make the kotlin compiler to generate [Snippet 5]

export interface ServiceConfiguration {
  appId: string;
  debug?: boolean // want this to be optionally provided
}

instead of the one being generated on [Snippet 2].

So that I may use it as written in [Snippet 3]?
