Incorrect TypeScript Definition for sentences()

I believe there is a TypeScript definition issue with sentences():

Error:

Property 'subjects' does not exist on type 'ExtendedDocument<{ sentences(n?: number | undefined): Sentences; }, World, Phrase>'.

TS Code:

import nlp from 'compromise';
import compromiseSentences from 'compromise-sentences';
const nlpEx = nlp.extend(compromiseSentences);

nlpEx('Hi bob').sentences().subjects();

Working on observablehq:

Oh right 😄 sentences(): ExtendedDocument<Ext, W, Ph> is a built in function (looks like it should actually take a parameter also…).

/** overload original sentences() method and return Sentence class**/
