Blinking Effect or New Color for latest coordinate

📊 Plotly Python
1

Hi

I would like to achieve the effect of blinking or to have a new color of the last coordinate that is being plotted for each step on the slider.

import plotly
import pandas as pd
import plotly.graph_objects as go

df = pd.DataFrame(
    {'City': ['Buenos Aires', 'Brasilia', 'Santiago', 'Bogota', 'Caracas'],
     'Country': ['Argentina', 'Brazil', 'Chile', 'Colombia', 'Venezuela'],
     'lat': [-34.58, -15.78, -33.45, 4.60, 10.48],
     'lon': [-58.66, -47.91, -70.66, -74.08, -66.86]})

fig=go.Figure(go.Scattermapbox(
               lat=[df.loc[0, 'lat']],
               lon=[df.loc[0, 'lon']],
               mode='markers',
               marker=dict(size=10, color='red')
            ))
        

fig.update_layout(mapbox=dict(#accesstoken=mapbox_access_token,
                              bearing=0,
                              pitch=0,
                              style='carto-positron'))
frames = [go.Frame(data= [go.Scattermapbox(
