I wrote this very simple script

import requests
import gradio as gr
import json

def chat_response(message, history, response_limit):
    return f"You wrote: {message} and asked {response_limit}"

with gr.Blocks() as demo:
    gr.Markdown("# Data Query!")
    with gr.Row():
        with gr.Column(scale=3):
            response_limit = gr.Number(label="Response Limit", value=10, interactive=True)
        with gr.Column(scale=7):
            chat = gr.ChatInterface(fn=chat_response,additional_inputs=[response_limit])

demo.launch()

with this I got something like

Do you notice the huge blank space below the chat and how small the window for the chat is?

I would like the chat space to extend all the way to the bottom (or if I put something else below, for all the elements in the column to ocuppy the whole screen

How can I do this?
