I am creating an Azure function (C# using dotnet core 3.1) that will call
the Google Ads API. Since this application has no UI I believe that I need
to use a service account to authenticate.
The code runs and returns an error "authenticationError": "NOT_ADS_USER"
The login that I used to create the service account is a google ads user in
the ads portal with a role of Admin.
The developer token used has basic access and the manager account is linked
to the customers account.
The full code and error message is listed below.
*What am I missing?*
GoogleAdsConfig config = new GoogleAdsConfig()

Google.Ads.GoogleAds.Config.OAuth2Flow.SERVICE_ACCOUNT,

OAuth2PrnEmail =

OAuth2Scope = "https://www.googleapis.com/auth/adwords";,
DeveloperToken = "********"
};
var responseMessage = "";
var client = new GoogleAdsClient(config);
// Get the GoogleAdsService.
GoogleAdsServiceClient googleAdsService =
client.GetService(Services.V6.GoogleAdsService);
// Create the query.
string query =
@"SELECT
