Hi,
I cannot find an answer, so I am writing here.
I represent the Shoper platform, I am wondering how to make your report aware of the larger scale of shops of our solution. Currently I see literally a dozen or so and it should be several thousand 
thanks.
We use Wappalyzer for the technology detections used by the CWV Tech Report. A first step to getting listed in the report would be to add your detections to Wappalyzer on GitHub.
You can learn more about the methodology in this post: New dashboard: the Core Web Vitals technology report
