Access to myopenhab.org (for Google Assistant) with the option "Implicit User Role" disabled

Hi everyone, I would like to be able to control my items with Google Assistant (Google Home) by leaving the “Implicit User Role” option disabled in the API security settings. But as soon as it is disabled, I no longer have access from Google Home or otherwise via myopenhab.org. Is there any solution using api token or user and password for openhab cloud?
