Getting everything to work:

$ betterdiscordctl install
If that fails, just clean discord by deleting ~/.config/discord

Get this example css script:
https://github.com/AryToNeX/Glasscord/blob/master/extras/discord_example_theme/discord_example.theme.css

Save it in custom css in discord BD settings.
Maybe change --glasscord-titlebar there from osx to windows or linux (normal window)
