This is the link, the code is running on Google Colab, and not something that is running all day.
However on the server side there is nothing besides:

#Colab Side:
import folium
m = folium.Map(location=[45.5236, -122.6750], zoom_start=13)
@anvil.server.callable
def get_map_html():
  html_string = m.get_root().render()
  return html_string
