company.com
is called the zone apex (where the name is the same as the zone). A zone apex cannot be a 
CNAME
- that is a limitation of DNS.

Therefore you cannot use the K277 method, as that describes delegating some other zone to the GTM (called 

wip
) and pointing 
CNAME
records at it.

If you need 

company.com
to be a Wide IP, your GTMs must be authoritative for that zone so that it can answer queries for 
company.com
directly.
