Receiving Insufficient Permission error from DirectoryService

2 options:

1. You didn't include the right Scope. Are you sure that DirectoryService.Scope.AdminDirectoryOrgunit, DirectoryService.Scope.AdminDirectoryUser are enough?
2. Did you enable the API in the Console? More information is available at: https://developers.google.com/api-client-library/dotnet/get_started#auth, Look for your project in https://console.cloud.google.com/project and make sure that you enabled the Directory Admin API.

Please update this thread if one of these options worked or something else is still missing for you.
