python plotly - produce plot upon two clicks

Question

Let's suppose I have a plotly graph_objects.Figure object containing a scatterplot:

y = np.random.rand(10)
x = np.random.rand(10)
names = ['A', 'B', 'C', 'D', 'E',
        'F', 'G', 'H', 'I', 'L']
fig = go.FigureWidget()
fig.add_trace(go.Scatter(
                x=x,
                y=y,
                name='Base scatter',
                mode='markers',
                marker=dict(size=7),
                customdata = names,
                hovertemplate= '<b>x:</b> %{x}<br><b>y:</b> %{y}<br><b>Name:</b> %{customdata}<br>'))

fig.update_layout(title='Test')
fig.show()

Which produces the following image:

I would like that upon click on two different points, a new temporary plot appears with information about the two points (e.g. those two points in another canvas connected by a line).

I've looked into click handlers but I can't figure out how to make it work.

Thanks
