It is now possible to add configurations manually for electron

When starting an electron instance for the first time, a config.json file is initialized in the most relevant place based on the default settings of the operating system:

• %APPDATA% on Windows
• $XDG_CONFIG_HOME or ~/.config on Linux
• ~/Library/Application Support on macOS

Once created, it is possible to manually edit this file to add new configurations. See the backends section for more details.
