Splitting a dual y-axis draft into two panels

This AI draft overlays the number of inquiries and the average handling time (minutes) by day on one Axes with a dual y-axis (twinx()). Where the two lines meet or pass each other depends on how the range of the right y-axis is set, so it means nothing.

Change two lines of code to split the chart into two panels, one above the other (2 rows, 1 column), and share only the x-axis so the days line up. Put the inquiries in the top panel and the handling time in the bottom panel, and keep the y-axis labels and the title as they are.

Code to fix

import matplotlib.pyplot as plt

days = ["Mon", "Tue", "Wed", "Thu", "Fri"]
inquiries = [120, 135, 128, 150, 170]
minutes = [6.5, 7.0, 6.8, 8.2, 9.5]

fig, ax = plt.subplots()
ax.plot(days, inquiries, marker="o")
ax.set_ylabel("Inquiries")
ax2 = ax.twinx()
ax2.plot(days, minutes, marker="s", linestyle="--")
ax2.set_ylabel("Handling time (min)")
ax.set_title("Inquiries and handling time")
plt.show()
