Event system for brain and evoked plots(GSoC)

Hello everyone,
I have also started looking into the idea of integrating the 3D brain viewer with time-based viewers for GsoC 2023 in the ideas list(GSoC Ideas 路 mne-tools/mne-python Wiki 路 GitHub).
Im assuming that this idea includes integrating evoked data functions like plot_topomap with mne.viz.brain ?
I was also wondering if this has to do with working with pyvistaqt ? I am looking for a bit more clarity on what this idea鈥檚 about and maybe where i can get started.

Thanks In Advance!
