copying google doc file in shared drive using c# - google-docs-api

Question

We have been using google drive for a while now to select an existing doc, owned by one of our employees, copy it and then merge data into placeholder fields to then download a pdf version of the doc. It's been working fine except now other employees want access to the created docs. So when we give them a link, the original employee has to give them access. We want to move the docs to a shared drive where all employees can see anything in the shared drive. From what I could find in google on this, it looks like we need to set the SupportsAllDrives property to true on the request. However, I can't find that property on any of the objects that we're creating when copying the base document. Because of this I keep getting a 404 from google when trying to copy the file. Can anyone suggest how to get this working?
var secrets = new ClientSecrets
{
ClientId = GoogleCredentials.accesskey,
ClientSecret = GoogleCredentials.secretkey
};
var refreshToken = _credService.GetRefreshToken();
if (string.IsNullOrEmpty(refreshToken))
{
throw new Exception("Missing google refresh token for google doc processor task.");
}
var token = new TokenResponse { RefreshToken = refreshToken };
var credentials = new UserCredential(new GoogleAuthorizationCodeFlow(
new GoogleAuthorizationCodeFlow.Initializer
{
ClientSecrets = secrets
}),
"user",
token);
var docService = new DocsService(new BaseClientService.Initializer
{
HttpClientInitializer = credentials,
ApplicationName = "Contract Merge"
});
var driveService = new DriveService(new BaseClientService.Initializer
{
HttpClientInitializer = credentials,
ApplicationName = "Contract Merge"
});
var newTitle = "Agreement for " + contract.FirstName + " " + contract.LastName + " " + DateTime.Now.Month.ToString() + "-" + DateTime.Now.Day.ToString() + "-" + DateTime.Now.Year.ToString();
var newFile = new google.Apis.Drive.v2.Data.File { Title = newTitle };
var documentCopyFile = driveService.Files.Copy(newFile, GoogleConstants.TemplateDocId).Execute();

As you can see in the C# library reference, an optional query parameter like supportsAllDrives (see query parameters on the API docs) is handled by a property of the CopyRequest class.
Therefore, after building the CopyRequest, but before executing it, you have to set the property SupportsAllDrives to true, as shown here:
FilesResource.CopyRequest copyRequest = driveService.Files.Copy(newFile, GoogleConstants.TemplateDocId);
copyRequest.SupportsAllDrives = true;
copyRequest.Execute();

Class FilesResource.CopyRequest
