The docs provide an example of how amp-consent might be used with amp-analytics

Is it possible to use Google Analytics on AMP (Accelerated Mobile Pages) Pages without cookies?

If yes, how should it be configured?

Because of the General Data Protection Regulation (EU) 2016/679 (GDPR) the user of a website has to give its consent to store (tracking)-data on users computer. We want to use Google Analytics on AMP (Accelerated Mobile Pages) anyway. Currently we doing it with <amp-pixel> and the analytics API, but this is only a superficial tracking. Is it possible to use <amp-analytics> and disable cookie like the “desktop-version” of the analytics-script?

Thanks, for help
