--help-config does nothing

[ghost]

kitty-theme --help-config only outputs an error message that says:

usage: kitty-theme [-h] [--version] [-d] [-v] [-c CONFIG] [-l] [-s] [-T TEST_THEME] [-t] [--setd DARK_THEME] [--setl LIGHT_THEME] [-L] [--help-config] kitty-theme: error: argument -c/--config: The configuration file must exist. Use --help-config to see how to configure the Kitty Theme Changer.

I have no idea what I'm meant to do.
