Not able to call multiple Custom React Components

Using Streamlit
1

Summary

I need to call multiple ReactJS custom components in a streamlit app.
I am following this link by Fanilo ANDRIANASOLO for calling components. This link talks about calling a single component but , if I need to call more components, I need guidance.

This link talks about how we could do so, but I am not able to follow the same . I tried the second approach but don’t know how to call args in index.tsx as stated in the link above .
@andfanilo and other stalwarts, please help.

Steps to reproduce

my project setup is exactly like the one provided in this link:

Code snippet:
app.py :

import streamlit as st
from streamlit_custom_slider import st_custom_slider 
from streamlit_ws_localstorage import injectWebsocketCode, getOrCreateUID

v_custom = st_custom_slider('Hello world', 0, 100, 50, key="slider1")
st.write(v_custom)

Code snippet:
init .py:

import os
import streamlit.components.v1 as components
from typing import Tuple
_RELEASE = True
_component_func = components.declare_component( 
        "custom_slider", 
        url="http://localhost:3001",
    )
def st_custom_slider(label: str, min_value: int, max_value: int, value: int = 0, key=None) -> int:
    component_value = _component_func(label=label, minValue=min_value, maxValue=max_value, initialValue=[
                                       value], key=key, default=[value])
    return component_value[0]


v_custom = st_custom_slider('Hello world', 0, 100, 50, key="slider1")
st.write(v_custom)

Code snippet:
init .py:

import os
import streamlit.components.v1 as components
from typing import Tuple
_RELEASE = True
_component_func = components.declare_component( 
        "custom_slider", 
        url="http://localhost:3001",
    )
def st_custom_slider(label: str, min_value: int, max_value: int, value: int = 0, key=None) -> int:
    component_value = _component_func(label=label, minValue=min_value, maxValue=max_value, initialValue=[
                                       value], key=key, default=[value])
    return component_value[0]


v_custom = st_custom_slider('Hello world', 0, 100, 50, key="slider1")
st.write(v_custom)

Now, in streamlit_custom_slider/frontend/src/
there are “CustomSlider.tsx” & “CustomSlider2.tsx” & “index.tsx”

Code snippet:
index.tsx:
Here, How Could I call multiple react components

iimport React from "react"
import ReactDOM from "react-dom"
import CustomSlider from "./CustomSlider"

// Lots of import to define a Styletron engine and load the light theme of baseui
import { Client as Styletron } from "styletron-engine-atomic"
import { Provider as StyletronProvider } from "styletron-react"
import { ThemeProvider, LightTheme } from "baseui"

const engine = new Styletron()

// Wrap your CustomSlider with the baseui them
ReactDOM.render(
  <React.StrictMode>
    <StyletronProvider value={engine}>
      <ThemeProvider theme={LightTheme}>
        <CustomSlider />
      </ThemeProvider>
    </StyletronProvider>
  </React.StrictMode>,
  document.getElementById("root")
)

P.S. I cant create a public repository of the components. This will be used internally
