python - How can I plot the maximum Y value on line graph from a dataframe

I'd like to be able to show the maximum y value only on the chart below.

enter image description here

code found below

enter image description here

fig = plt.figure(figsize=(15,10))
axes = fig.add_axes([0.1,0.1,0.8,0.8])
sns.set_style('whitegrid')
sns.lineplot(x=df['Displacement'],y=df['Force'],data=df, palette="tab10", linewidth=2.5)
axes.set_xlabel('Displacement in X direction [mm]')
axes.set_ylabel('Applied Force [N]')
axes.set_title('Displacement vs Applied Force')

I've had a look, but most solutions use a list rather than a dataframe, I'm out of ideas.
