[Ananth09]

When I use st.navigation or st_navigation_bar, the navbar option are not seen.
For example
Using:
import streamlit as st
from streamlit_navigation_bar import st_navbar
page = st_navbar([“Main”, “Derived”])
st.write(“Food”)
This is seen:

Ive tried running it in multiple browsers and incognito tabs aswell
Im using streamlit 1.43.2 and python 3.13.2
