Google Ads Enhanced Conversion

Hello there,

I'd like to integrate Google Enhanced Conversions https://support.google.com/google-ads/answer/9888656?hl=en in my website.

Since personal data about users (email, name, surname etc) in shared with Google, I was wondering if I need to integrate something in the privacy/cookie policy of the site but I cannot find a specific service for this functionality. 

Can you add this to the service list? Is it necessary, in the first place?

Thanks,

Matteo
