using namespace independentsoft::graph;
using namespace independentsoft::graph::mails;

int main()
{
    try
    {
        GraphClient client;

        client.client_id = "63333333-209e-454e-b7bd-55a4d201270f";
        client.tenant = "independentsoft.onmicrosoft.com";
        client.client_secret = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";

        FileAttachment attachment;
        attachment.name = "document.txt";
        attachment.content_type = "text/plain";

        std::string text = "Hello, World!";
        attachment.content = Util::bytes(text.begin(), text.end());

        MessageId messageId("message-id-123");
        std::shared_ptr<Attachment> newAttachment = sync_wait(client.create_attachment(attachment, messageId));

        std::cout << "Id = " << newAttachment->id << std::endl;
        std::cout << "Name = " << newAttachment->name << std::endl;
    }
    catch (const GraphException& ex)
    {
        std::cout << "Error: " << ex.code << std::endl;
        std::cout << "Message: " << ex.message << std::endl;
