Change the size of axes labels on a line chart

Hi! I’m trying to change the sizes of the X axis label and Y axis label for my line chart. How can I do this? My current code for the layout is as follows:

Edit the Layout:

fig.update_layout(
title_text=f"Service Trend Analysis {Year}",
title_x= 0.5,
title_font_size=30,
title_font_color="#351C15",
xaxis_title= “Month”,
yaxis_title= ‘Services’,
autosize=False, width=1200, height=700,
showlegend=True)

fig.show()

Thank you!!
