- Generally if the Vendor doesn't supply the data you would have to try and look it up in another Table.
By the way you could have used ASIM for this (simple example):
_Im_NetworkSession_PaloAltoCEFV06(starttime=ago(1d))
// or use _ASim_NetworkSession if you dont need a parameter https://docs.microsoft.com/en-us/azure/sentinel/network-normalization-schema
| where Activity =~"Threat"
| distinct DstGeoCountry, SrcGeoCountry
note: GeoCountry are optional in the schema

this is correct line.
