1. I have correctly authorised myself to the controlling account
2. I can demonstrate this by calling ListAccessibleCustomers and have it return a suitably long list of clients
4. When I execute the code I invariably get:
Unhandled Exception: Google.Ads.GoogleAds.V10.Errors.GoogleAdsException: Status(StatusCode="PermissionDenied", Detail="The caller does not have permission", DebugException="Grpc.Core.Internal.CoreErrorDetailException: {"created":
"@1653366827.845000000","description":"Error received from peer ipv4:
142.250.70.202:443","file":"..\..\..\src\core\lib\surface\call.cc","file_line":1070,"grpc_message":"The caller does not have permission","grpc_status":7}")
5. I have tried to generate a trace using TraceUtilities.Configure(TraceUtilities.DETAILED_REQUEST_LOGS_SOURCE, path, System.Diagnostics.SourceLevels.All); but that seems only to be created when the operation is successful and in this case it is not.
