Typescript cannot prompt literal

[Elinor Fahey (Zz-ing)]

I added a function declaration via addExtraLib and the incoming parameter is a literal, but my Monaco-editor has no prompt for literals, and vscode has.

const JavaScriptEditor: React.FC<JavaScriptEditorProps> = ({ value, onValueChange }) => {
  const handleEditorValueChange = (
    value: string | undefined,
    _ev: editor.IModelContentChangedEvent
  ) => {
    onValueChange?.(value ?? '')
  }
  const handleEditorDidMount = (editor: IStandaloneCodeEditor, monaco: Monaco) => {
    monaco.languages.typescript.typescriptDefaults.addExtraLib(
      'declare class MyApi {static hello1(a: "test" | "test2"): string;}'
    )
  }

  return (
    <div className={s.javascriptEditorContainer}>
      <div className={s.javascriptEditor}>
        <Editor
          language={'typescript'}
          value={value}
          onChange={handleEditorValueChange}
          className={s.javascriptEditorInput}
          loading={<></>}
          onMount={handleEditorDidMount}
          options={defaultMonacoEditorOptions}
        />
      </div>
      <div className={s.javascriptContextPrompts}>
        <div className={s.javascriptContextTree}></div>
        <div className={s.javascriptContextDescription}></div>
      </div>
    </div>
  )
}
