Reproducing chatinterface submit button

Iā€™m using blocks. I would like to reproduce the look of the submit button that sits next to the input box in the chatinterface with the orange button is connected to the text input. Like here:

Is there any easy way to do this? I want to submit button to sit next to the msg input box

with gr.Blocks() as demo:
    chatbot = gr.Chatbot()
    msg = gr.Textbox()
    clear = gr.ClearButton([msg, chatbot])
