Scattermapbox cluster do not work

Clustering of scatter points on a map do not form even though the documentation indicates this should work:
https://plotly.com/r/reference/scattermapbox/#scattermapbox-cluster

It seems to work in Plotly for Python:
https://plotly.com/python/scattermapbox/

Below is a reproducible example. Please use your own mapbox token.

Sys.setenv("MAPBOX_TOKEN" = mapboxtoken)
df = read.csv('https://raw.githubusercontent.com/bcdunbar/datasets/master/meteorites_subset.csv')
fig <- df %>% plot_mapbox(lat = ~reclat, lon = ~reclong,
                          size=2, type = 'scattermapbox',
                          mode = 'scattermapbox', hoverinfo='name',
                          cluster = list(enabled = TRUE, step = -2, color = 'red')) 
fig <- fig %>% layout(title = 'Meteorites',
                      font = list(color='white'),
                      plot_bgcolor = '#191A1A', paper_bgcolor = '#191A1A',
                      mapbox = list(style = 'dark'),
                      legend = list(orientation = 'h',
                                    font = list(size = 8)),
                      margin = list(l = 25, r = 25,
                                    b = 25, t = 25,
                                    pad = 2)) 
fig <- fig %>% config(mapboxAccessToken = Sys.getenv("MAPBOX_TOKEN"))
fig

Warning message:
'scattermapbox' objects don't have these attributes: 'cluster'

Cluster formation using Plotly for Python

Inizia eseguendo l’esempio R riproducibile usando il riferimento ai cluster scattermapbox collegato e conferma l’avviso secondo cui l’attributo cluster non è supportato. Confronta il risultato R con l’esempio Plotly Python collegato; l’attività è completata quando la trace scattermapbox di R accetta le impostazioni cluster documentate e forma i cluster.
