Returns a time-based one-time password based on the
            Google Authenticator password algorithm. Works with Authy.
            If "totp_key" is not specified, defaults to using the one
            provided in seleniumbase/config/settings.py
            Google Auth passwords expire and change at 30-second intervals.
            If the fetched password expires in the next 1.5 seconds, waits
            for a new one before returning it (may take up to 1.5 seconds).
            See https://pyotp.readthedocs.io/en/latest/ for details.
