How to add the poligon of frecuencies to px.histogram?

Dash Python

hi, I have a histogram

    figure = px.histogram(data_frame=dff2_,
               x=dff2_[drop1],
               marginal='violin',
               histnorm='probability density',
               title="Histogram %s "%drop1,
               )

is there a straight parameter to see this (the curve)?:
