[Python] Set fontsize of axis and legends in seaborn.objects

I am using seaborn.objects to create a faceted plot. I have read the documentation but setting font size argument does not do anything (Seaborn.objects Documentation)

My Df:

{'storage': {0: '4 °C',
1: '4 °C',
2: 'fresh',
3: 'fresh',
4: 'frozen',
5: 'frozen',
6: '4 °C',
7: '4 °C',
8: 'fresh',
9: 'fresh',
10: 'frozen',
11: 'frozen',
12: '4 °C',
13: '4 °C',
14: 'fresh',
15: 'fresh',
21: 'fresh'},
'time': {0: '4 h',
1: '6 h',
2: '4 h',
3: '6 h',
4: '4 h',
5: '6 h',
6: '4 h',
7: '6 h',
8: '4 h',
9: '6 h',
10: '4 h',
11: '6 h',
12: '4 h',
13: '6 h',
14: '4 h',
15: '6 h',
21: '6 h'},
'Predicted Class': {0: 'resting',
1: 'resting',
2: 'resting',
3: 'resting',
4: 'resting',
5: 'resting',
6: 'swollen',
7: 'swollen',
8: 'swollen',
9: 'swollen',
10: 'swollen',
11: 'swollen',
12: 'germling',
13: 'germling',
14: 'germling',
15: 'germling',
21: 'hyphae'},
'%': {0: 25.57,
1: 4.87,
2: 12.19,
3: 4.87,
4: 99.87,
5: 99.77,
6: 72.89,
7: 60.23,
8: 86.93,
9: 42.83,
10: 0.13,
11: 0.23,
12: 1.54,
13: 34.9,
14: 0.88,
15: 51.4,
21: 0.9}}


import seaborn.objects as so


# Create the Plot object
plot = so.Plot(counts2_melted_df, x="storage", y="%", color="Predicted Class", text="%")

# Facet the plot by 'strain' with an increased height for each row
plot = plot.layout(size=(8,8)) # Adjust the scale factor for height

# Add the bar and stack
plot = plot.add(so.Bar(), so.Stack()).scale(color=color_palette)

plot = plot.label(x="Storage Condition", y="Percentage of Morphotype (%)")

plot= plot.theme({"axes.facecolor": "w", "axes.edgecolor": "slategray"})

plot = plot.facet(row="time")

#Render the plot to get the underlying matplotlib axes
plot.plot()


I have tried

plot = plot.label(x="Storage Condition", fontsize=28)
plot = plot.label(y="Percentage of Morphotype (%)", fontsize=28)


Any suggestions? I need to increase the font size drastically to make the plot readable on a poster.

I would be grateful for any help!
