You want the Postmaster Console for delivery and abuse issues, not the Search Console which is probably why you couldn't find anything.

If you've already verified your domains in the search console it is one click to add them. https://postmaster.google.com/

I think you misunderstand. I did challenge the flag in the correct place in Google's byzantine UIs. I just don't remember today exactly which UI that was.

The flag was raised against web content on our domain - it claimed our online demo was a phishing site - not on use or content of our email.
