Running the Linux bin: twitch-cli_1.1.5_Linux_x86_64.tar.gz

In twitch -h there is talk about a --config param, but when I try to use it, it appears to be ignored and the default location is used.

Flags:
      --config string   config file (default is $HOME/.twitch-cli/.twitch-cli.env)
  -h, --help            help for twitch

Command run to set the config file:
twitch token --config "/.twitch-cli.env"

What am I doing wrong?

PS, the default config location is also incorrect in the -h text, it's: $HOME/.config/twitch-cli/.twitch-cli.env (at least in the linux binary).
