Add features to the datapoints on map using

Hi team, I would like to add some datapoints to the map. I found that displays a map with point on it. Any idea how I can add text to the datapoints and/or change their color, size etc? I also found that st.deck_gl_chart adds layer however this is what I get:

AttributeError: module ‘streamlit’ has no attribute ‘deck_gl_chart’

I’m working with the Python 3.8.3 and Streamlit 0.88.0. Any help would be appreciated.
