Remove/delete previously verified unwanted domains

[hvjunk]

Good day,
I've previously (for a client's PoC) verified some domains to my account's AppEngine, 

but now they are still listed whenever I do:

  gcloud domains list-user-verified

and I can't find a way to delete them :(

Who/what/where do I contact to remove these extraneous domains?

Hello Hendrik,

It seems like you are having an issue with the deletion your custom domains from your App Engine app. To do this, you need to go to Custom Domains page and click on the bin button next to your domain to remove it.

I hope this helps you to resolve the issue.
