`` using (var sender = new Sender(serverKey))
{
var message = new Message
{
RegistrationIds = new List() { tokensUser },
Notification = new Notification
{
Title = "musicScope",
Body = description,
},
Data = new
{
tag = new Guid().ToString(),
id = new Random().Next(1, 9000000),
parameter = parameter,
type = notification,
typeGallery = typeGallery
}
};

            var result = await sender.SendAsync(message);
        }
