Cannot use st.set_page_config

[mirfan899]

cannot use set_page_config in multiapp. Throws following error.

from mapp import MultiApp
import app1
import app2
import streamlit as st
st.set_page_config(
    page_title="The Entities Swissknife",
    page_icon="https://cdn.shortpixel.ai/spai/q_lossy+ret_img+to_auto/https://studiomakoto.it/wp-content/uploads/2021/08/cropped-favicon-16x16-1-192x192.png",
    menu_items={
        "Get help": None,
        "Report a bug": None,
        "About": None
    }
)
app = MultiApp()
app.add_app("Foo", app1.app)
app.add_app("Bar", app2.app)
app.run()

This is my code where I'm using set_page_config method.

streamlit run app.py
