Get text response from Stream response

So I am creating a stream of response from `createRetrievalChain` from Langchain JS. The whole code is ` const chain = await createStuffDocumentsChain({

llm: model,

prompt: prompt,

});

const conversationChain = await createRetrievalChain({

combineDocsChain: chain,

retriever: retrieverChain,

});

// check for question each time

const outputChain = RunnableSequence.from([

conversationChain,

new RunnablePick({ keys: "answer" }),

new HttpResponseOutputParser({ contentType: "text/plain" }),

]);

const response = await outputChain.stream({

chat_history: chatHistory,

input: question,

});`. In the FrontEnd I am using Vercel AI SDK in Next.JS to stream the response. While everything looks good to me and is working properly, but I also want to get the textual response from this Stream response, beacuse I have to store this textual response to DB. How I can do this with the help of Langchain or Vercel AI SDK?
