How to Send and Display a Link from Function Call to Frontend in LiveKit and agent-playground?

[zxh263]

I want to ask a question about LiveKit: The result contains a link. When this function call is invoked, I want to send this link to the frontend and display it in the chat window of the agent-playground project or in a separately developed component. How can this be implemented?

@llm.ai_callable()
async def take_photo(self):
"""This function is called when the user requests to take a photo. It captures an image from the latest video frame and saves it."""
call_ctx = AgentCallContext.get_current()
message = "Okay, I'll take a photo for you."
speech_handle = await call_ctx.agent.say(message) # noqa: F841
call_ctx.chat_ctx.append(text=message, role="assistant")

    logger.info("Capturing and saving the image")
    # Access JobContext via self.job_context
    latest_image = self.job_context.proc.userdata.get("latest_image", None)
    if latest_image is None:
        logger.error("No available image frame.")
        return "No available image."

    #result = await capture_image(latest_image, "photo")
    result=await save_frame(latest_image)
    # Return the path
    return result
