Sending notifications to mobile devices using firebase Firebase Admin

Question

I'm trying to send notifications to mobile devices using firebase admin sdk with asp.net mvc... But I'm stuck a certain request limit. Is there any way to get around this limit? I share some snippets of my code below.

var path = HttpContext.Current.Server.MapPath("~/assd.json");
var path = HttpContext.Current.Server.MapPath("~/assd.json");
FirebaseApp.Create(new AppOptions()
{
    Credential = GoogleCredential.FromFile(path),
    ProjectId = "*********",
});

var message = new MulticastMessage
{
    Data = new Dictionary<string, string>()
         {
            { "type", type },
            { "typeValue", typeValue },
            { "isSound", isSound.ToString()},
            { "title", title},
            { "body", spot },

         },
    Apns = new ApnsConfig()
    {
        Headers = new Dictionary<string, string>()
    {
        { "apns-priority", "10" },
    },
        Aps = new Aps()
        {
            Alert = new ApsAlert()
            {
                Title = title,
                Body = spot,
            },
            Badge = 1,
        },
    },
    Tokens = tokens,
};

var response =FirebaseMessaging.DefaultInstance.SendMulticastAsync(message).Result;
if (response.FailureCount > 0)
{
    var failedTokens = new List<string>();
    for (var i = 0; i < response.Responses.Count; i++)
    {
        if (!response.Responses[i].IsSuccess)
        {
            failedTokens.Add(tokens[i]);
            listLog.Add(tokens[i]);
        }
    }
}

I also try to use the topic system, but it also has a limit.
