After "fig.show()", there was no any result

Thank you for this nice tool! I would like to use it to plot surfaces, but I seem to have a slight problem while repeating the steps of the tutorial....
I ran the program on jupyter lab.
''from neuromaps.datasets import fetch_fslr
surfaces = fetch_fslr()
lh, rh = surfaces['inflated']

from surfplot import Plot
p = Plot(surf_lh=lh, surf_rh=rh)
fig = p.build()
# show figure, as you typically would with matplotlib
fig.show()"

There was no error warning, but after "fig.show()", there was no any result.

The result is shown in the figure. (ps,the cells have already been run )

Looking forward to getting your answer, thank you!
