Access newQuestion in ConversationalRetrievalQAChain

[phof]

With reference to https://github.com/langchain-ai/langchainjs/blob/main/langchain/src/chains/conversational_retrieval_chain.ts#L172C9-L209

Is there a way to access the newQuestion generated as part of the questionGeneratorChain?

E.g.:

const chain = new ConversationalRetrievalQAChain({
  verbose: true,
  retriever: vectorStore.asRetriever(docstoretrieve),
  memory,
  returnSourceDocuments: true,
  outputKey: 'output',
  combineDocumentsChain: docChain,
  questionGeneratorChain: questionGenerator,
})
const query = await chain.call({ question })
// how do I access `newQuestion` here?
