Dash leaflet - Marker cluster groups by column of geojson

Dash Python
1

Hi. I am trying to create a dash_leaflet map with points from a geojson but it needs to cluster by country, which is one of the columns of the geojson.
I tried to use a previous version of dash_leaflet to use the dl.MarkerClusterGroup and it worked. But how could I do this with the new version of dash_leaflet ?

I tried this :

def plot_portal_map_leaflet(satellite_image:str="https://server.arcgisonline.com/ArcGIS/rest/services/World_Imagery/MapServer/tile/{z}/{y}/{x}.png"):
    return dl.Map(
        [
            dl.TileLayer(url=satellite_image),
            dl.GeoJSON(
                url="assets/points.geojson",
                cluster=True,
            ),
        ],
        style={"height": "100%"},
        center=[24, 12],
        zoom=2.1,
    )

But it seems like I can’t tell the clusters to be by the “country” column…
