I have export AWS_CONFIG_FILE="$XDG_CONFIG_HOME/aws/config" in my zsh profile for xdg compliance, when running sesh, all my configured profiles don't appear although I can use them normally with the aws command line. it's probably good to also add support for people setting the AWS_SHARED_CREDENTIALS_FILE, for example I have it set to AWS_SHARED_CREDENTIALS_FILE="$XDG_DATA_HOME/aws/credentials"
