Hi @ritwik_lal, welcome to the Streamlit community!
It’s important to note that st.map() is a convenience function for quickly plotting on a map. If you want to be more involved, there are several choices.
Within Streamlit, there’s a second function st.pydeck_chart that allows you to write a Deck.gl specification through Python to create customized layers:

Additionally, I just released a Streamlit Component for Folium:

Best,
