about google analytics, 'client_storage': 'none', 'anonymize_ip': true opts

[MrGreensWorkshop]

Hi, I was just passing by,

I read the documentation about disabling google analytics

its looks like, these are the ways to disable or disabling ad_storage and analytics_storage at startup

<script>
window['ga-disable-MEASUREMENT_ID'] = true;
</script>

<script>
// Define dataLayer and the gtag function.
window.dataLayer = window.dataLayer || [];
function gtag(){dataLayer.push(arguments);}

gtag('consent', 'default', {
  'ad_storage': 'denied',
  'analytics_storage': 'denied'
});
</script>

I couldn't find anything about these options in googles documentation

'client_storage': 'none', 'anonymize_ip': true

GlowCookies/src/glowCookies.js

Line 187 in 2cf4bfd

'client_storage': 'none',

could you please explain or refer any google documentation?
Thank you.
