def add_text(*args):
    pass

def add_file(*args):
    pass

def bot(*args):
    pass

with gr.Blocks() as demo:
    chatbot = gr.Chatbot([], elem_id="chatbot", height=750)

    with gr.Row():
        with gr.Column(scale=0.85):
            txt = gr.Textbox(
                show_label=False,
                placeholder="Enter text and press enter, or upload an image",
                container=False,
            )
        with gr.Column(scale=0.15, min_width=0):
            btn = gr.UploadButton(label="📁", file_types=["image", "video", "audio"])

    txt_msg = txt.submit(add_text, [chatbot, txt], [chatbot, txt], queue=False).then(
        bot, chatbot, chatbot
    )
    txt_msg.then(lambda: gr.update(interactive=True), None, [txt], queue=False)
    file_msg = btn.upload(add_file, [chatbot, btn], [chatbot], queue=False).then(bot, chatbot, chatbot)
    btn.upload(dummy, [], btn )
