Does streaming option on tool's excute function is available?

[psxxj]

const submitUserMessage = async (content: string) => {
  'use server';

  const aiState = getMutableAIState<typeof AI>();
  aiState.update([
    ...aiState.get(),
    {
      role: 'user',
      content,
    },
  ]);

  const reply = createStreamableUI(
    <BotMessage tool="Loading...">
      <Skeleton className="w-2/3 mt-2" active />
    </BotMessage>
  );

  const bside = await streamText({
    model: openai('gpt-4o'),
    messages: aiState.get().map((info: any) => ({
      role: info.role,
      content: info.content,
      name: info.name,
    })),
    tools: {
      explainAnotherLanguage: {
        description: 'You explain the input by KOREAN',
        parameters: z.object({
          originSentence: z.string(),
          translatedSentence: z.string().describe('Korean translation of the input.'),
          wordList: z.array(
            z.object({
              word: z.string(),
              definition: z.string(),
            })
          ),
        }),
        execute: async function (response) {
          // stream the response for the generative UI
          console.log(response);
        },
      },
      // add more tools here
    },
  });

  reply.done();

  return {
    id: Date.now(),
    display: reply.value,
  };
};

I expected to tools execute function's input will stream. but it does not work...
How can I achieve it?
