how do I add axis title(x-axis and yaxis) for both the sub plots created using below code? if I use update_layout it creates axis titles for the top plot only

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

fig = make_subplots(
rows=2, cols=2,
subplot_titles=(“Plot 1”, “Plot 2”, “Plot 3”, “Plot 4”))

fig.add_trace(go.Scatter(x=[1, 2, 3], y=[4, 5, 6]),
row=1, col=1)

fig.add_trace(go.Scatter(x=[20, 30, 40], y=[50, 60, 70]),
row=1, col=2)

fig.add_trace(go.Scatter(x=[300, 400, 500], y=[600, 700, 800]),
row=2, col=1)

fig.add_trace(go.Scatter(x=[4000, 5000, 6000], y=[7000, 8000, 9000]),
row=2, col=2)

fig.update_layout(height=500, width=700,
title_text=“Multiple Subplots with Titles”)

fig.show()
