I use Google as my CMP in view of the 16 January requirement "Beginning January 16, 2024, publishers and developers using Google AdSense, Ad Manager, or AdMob will be required to use a Consent Management Platform (CMP)". In other terms, I have not changed anything except that I have removed my home-made popup about privacy policy, and I trust Google to deliver whatever messages it needs. I remember having done some Google privacy settings in the AdSense interface a few years ago, including a link to the Privacy Policy page on my websites; so I assumed that this will do the job

Today I learned about the tool "CMP Validator", which is a Chrome extension. I installed it on Chrome (which I never use). And bingo: the extension shows a report which is rather positive:

Technical Compliance Checks passed: 8, failed: 1, to do:3

That corresponds i.e. to the report I see for The Telegraph or other major websites.

However I am concerned about the "failed" checks. This is what "CMP Validator" tells about it:

TECHNICAL COMPLIANCE CHECKS: DID ALL CMP API REQUIRED COMMANDS RETURN A CORRECT RESPONSE?

Manual steps required for this check

This check fails if any of the following mandatory CMP API commands do not return an expected response: ping, AddEventListener, RemoveEventListener.

Policy Reference (TCF V2)

CMP API v.2.2 technical specification.

All CMPs must support the three required API commands: 'ping', 'AddEventListener', 'RemoveEventListener'.

Hmmmmmm I must admit I don't understand that clearly, as I even don't know what is an API and how to add commands. But I suppose that means: "In the Google popup, each website must have a link to its Policy page".

If the above is a correct assumption, where in the AdSense interface should I find a way to add these "required commands" and / or manually add a link to the Privacy Policy page on each of my websites?
