Applying css of message() using "from streamlit_chat import message"

Hello, I’m using message() using “from streamlit_chat import message”. I’ve used “is_user=True” to separate messages, but I’ve used css to adjust the color of the message box or the size of the text, but it doesn’t work. Can I know what to do?

(Additional Updates)
If I wanted to distinguish the messages on the left and the right by color, I confirmed that they were applied through developer mode. However, I wrote and executed the source code at the bottom, but the CSS was not reflected. Can you get the cause and solution?

import streamlit as st
from streamlit_chat import message

        .css-1meupwp > div{
            background: orange;

message("User message",is_user=True)
