Creating curved lines Python Plotly

In this tutorial (https://plotly.com/python/lines-on-maps/ 23), the lines connecting the points are curved. However I can’t seem to recreate this behavior when using mapbox, i.e. go.Scattermapbox. With Scattermapbox the lines created are straight as shown on this page https://plotly.com/python/lines-on-mapbox/ 10. Are there any options or workarounds to join points using curved lines when using mapbox?

Thanks in advance!

flight_paths = []
for i in range(len(flights)):
    fig.add_trace(
        go.Scattergeo(
            lon = [flights['START_LON'][i], flights['DEST_LON'][i]],
            lat = [flights['START_LAT'][i], flights['DEST_LAT'][i]],
            mode = 'lines',
            line = dict(width = 1,color = 'red'),
            
        )
    )
