How to add a title to visuz volcano plot

Question

I'm using bioinfokit.visuz.GeneExpression.volcano to create a volcano plot. I can't figure out how to apply a title. I'm not sure if there is an object and how/if to control it with matiplotlib. Everything I try fails.

I'm following their tutorial example:

from bioinfokit import analys, visuz
df = analys.get_data('volcano').data

visuz.GeneExpression.volcano(df=df, lfc='log2FC', pv='p-value',show=True)

A few things I've tried unsuccessful.

ax = visuz.GeneExpression.volcano(df=df, lfc='log2FC', pv='p-value',show=True)
ax.set_title('title')

fig, ax = plt.visuz.GeneExpression.volcano(df=df, lfc='log2FC', pv='p-value',show=True)
plt.title('title')

visuz.GeneExpression.volcano(df=df, lfc='log2FC', pv='p-value',show=True).set_title('title')
