Trying to decode what you mentioned - You have AEM Assets and DM license and you do not use AEM Sites. You want to implement insights on the assets.
As mentioned in the document AEM Asset insights is a reference implementation
1. Have the AA report suite defined
2. Have the right javascript snippet loaded on the page via Launch.
3. Ensure the img tag has data-aem-asset-id=‘image.UUID’ and data-trackable=‘true’ present for Asset Impressions. For Asset Click Insights, in addition to the above data attributes present at the <img> tag, the parent <a> tag must have a valid href value should be present.
4. Configure the AEM Asset Reporting Sync Job Scheduler and Assets Insights Report to get the data back to AEM Assets/ Else you can get the info in AA.
As you can see, the data in AA is captured using uuid (not based on filename). If your website is external to AEM, ensure 2&3 is done correctly to start streaming the data back to AA via Launch.
I am not sure of the ask of AA integration into Cloud manager. If it is anything about getting insights of your deployment pipeline, you have to use CM API endpoints and capture the data.
