clickData is not working for Gantt chart

Dash Python
1

Hi,
I am trying to implement interactive crossfiltering with Gantt chart, but clickData for this chart always returns None in my callback. I don’t have this issue with scatter plots. Is it supposed to work in Gantt chart or I am doing something wrong? Here is my code:

@app.callback(
Output('steps-time-series', 'figure'),
[Input('crossfilter-gantt', 'clickData')])
def update_figure3(clickData):
if clickData is not None:
    print(json.dumps(clickData, indent=2))
    plot = plots.plot_factory()
    return plot
else: return None

My library versions are:
dash 0.39.0
dcc 0.46.0
dhc 0.14.0
plotly 3.7.1
