Google Domains: "Name Conflict" when trying to add

I need to add a `cname` called "_domainconnect" for my domain name but every time I try Google just tells me "Name Conflict". There is not already a record with that name.


What gives?

Update: Response from Google:

Thanks for your patience. Please be informed that the reason as to why you are unable to add the record is because the hostname is already being used by Google Domains. You may not see it on the actual DNS settings of your domain name but it's automatically configured on the back end.

We do not have a way to remove it as well.
