Unable to authenticate using google-oauthlib-tool

(env) pi@jarvis:~ $ google-oauthlib-tool --client-secrets ./client_secret_858487554047-4corgtdi0ritlrs6.apps.googleusercontent.com.json --scope https://www.googleapis.com/auth/assistant-sdk-prototype --scope https://www.googleapis.com/auth/gcm --save --headless Error: no such option: --headless

I don't think --headless is documented as a supported flag. Where is this command sourced from?

--headless was removed in #264 because the OAuth feature it relied on (out-of-band) was turned down for security reasons.

I'm not aware of another general OAuth method to provide a headless experience like the one offered by --headless.
