Using hovering callback on GeoJSON features?

[deeplook]

There's a ton of excellent documentation, but I still seem unable to find the trick to replicate this code below using "pure" ipyleaflet in leafmap's ipyleaflet. Essentially I'd like to use a callback to access some GeoJSON properties when hovering over the respective features in order to do use this information somewhere else. If I can't find it it's because it is too simple, right? ;-)

import requests
from ipyleaflet import GeoJSON, Map

def handle_geojson_hover(event=None, id=None, properties=None, **kwargs):
    print(properties)

url = "https://raw.githubusercontent.com/giswqs/leafmap/master/examples/data/countries.geojson"
data = requests.get(url).json()
m = Map(center=(0, 0), zoom=2)
gj_layer = GeoJSON(data=data, hover_style={"color": "red", "fillColor": "red"})
gj_layer.on_hover(handle_geojson_hover)
m += gj_layer
m

Would this be acceptable?

import requests
from ipyleaflet import GeoJSON
from leafmap import Map

def handle_geojson_hover(event=None, id=None, properties=None, **kwargs):
    print(properties)

url = "https://raw.githubusercontent.com/giswqs/leafmap/master/examples/data/countries.geojson"
data = requests.get(url).json()
m = Map(center=(0, 0), zoom=2)
gj_layer = GeoJSON(data=data, hover_style={"color": "red", "fillColor": "red"})
gj_layer.on_hover(handle_geojson_hover)
m += gj_layer
m

Embarrassingly simple, indeed! Thanks!
