How to get bar chart in front of stacked area charts in sub_plots for python?

I have see code that nicely places bar charts infront of area charts using overlaying. But how can I create this in a sub_plot scenario?

Specifically I try to move the Scatter area behind the bars in this sub_plot:

from plotly.subplots import make_subplots
import plotly.graph_objects as go

fig = make_subplots(rows=1, cols=2)

fig.add_trace(
go.Scatter(x=[1, 2, 3], y=[4, 5, 6],
mode=โ€œlinesโ€,
fill=โ€œtonextyโ€,
yaxis=โ€œy1โ€,),
row=1, col=1
)
fig.add_trace(
go.Bar(x=[1, 2, 3], y=[4, 5, 6],
yaxis=โ€œy2โ€,),
row=1, col=1
)

fig.add_trace(
go.Scatter(x=[20, 30, 40], y=[50, 60, 70],
mode=โ€œlinesโ€,
fill=โ€œtonextyโ€,
yaxis=โ€œy3โ€,),
row=1, col=2
)
fig.add_trace(
go.Bar(x=[20, 30, 40], y=[50, 60, 70],
yaxis=โ€œy4โ€,),
row=1, col=2
)
fig.update_layout(height=600, width=800,
title_text=โ€œSide By Side Subplotsโ€,
yaxis1=dict(overlaying=โ€˜y2โ€™),
yaxis3=dict(overlaying=โ€˜y4โ€™))
fig.show()
