Creating a non-alias CNAME with Cloudflare?

To verify my domain, someone at Google requested me to create a CNAME with this:

Create the following CNAME record through your domain hosting provider:

Label/Host: deleteGAPPSnotBefore20171127utc

Destination/Target: case-XXXXX-for-example.com-at.google.com

Time to live (TTL): 3600

After creating it, I got this reply:

Unfortunately, we won´t be able to proceed with the process with the record reflecting as an alias. Please coordinate with your domain host and ask assistance in adding the provided record values as a CNAME record.

As much as I would love to accept the record you created as a proof of your domain ownership, our security policy requires us that the values be reflected in the proper record type.

Now, the definition itself says that CNAME is a type of record used to specify that a domain name is an alias for another domain.

The question is, what are these people from Google expecting me to do? How do I create a non-alias CNAME if a CNAME record is an alias by definition? There's no drop down box to select the CNAME type in Coudflare (and I guess in any other DNS panel for the matter).

This makes no sense, but I can't reply this to the Google support guy as they'll always stand their ground.
