Verification of callback URL when hosted on run.app (Google cloud)

Hi, I’m creating a Zoom App to use Zoom’s OAuth capabilities and being able to download recordings.
My call back URL points to my server which runs on Google cloud run. I tested the integration and everything works great, except that when I need to publish my app, it asks me to verify that I own the domains, which includes run.app which is actually owned by google, but happens to be where I run my server.
Please advice on how to proceed.
Many thanks.
