Custom 3D plot over mne.viz.Brain object

Hello,

I would like to add a custom 3D plot over a mne.viz.Brain plot. I believe the generated plot from that class is a PyVista object and hence, I am willing to complicate things for myself and use PyVista instead of Matplotlib to make my overlying custom 3D plot.

However, PyVista seems to require a handle for the figure to make the subsequent plot, and I don’t know how to get it from the mne.viz.Brain object. Does anyone know how to do that and/or are there other simpler ways to do this?

Thanks a lot!
