Have you considered CSD?

As https://blogs.gnome.org/tbernard/2018/01/26/csd-initiative/

That'd look great in GNOME!! 🥇

Actually I have that implemented. If you look into https://github.com/rockiger/akiee/blob/master/app/css/gnome.css You can uncomment the code that implements the csd. You then have to start electron frameless in package.json.

Since I am not using Gnome anymore, I dont't have any interest in CSD. I don't think the bring any value to the table and the look kind of alien in Plasma.
