How to send alert to telegram all at once of exploration result?

[dangin.gen]

Hi all,
Please help me to solve the problem base on my subject.
my telegram alert already running for one by one alert, but when my exploration got 10 stocks, i will receive 10 message in telegram.
i tried to modify my afl so that my exploration result send all at once to my telegram channel.
with this modify, i got too much messages repetition and this alert doesn't match with my exploration result.

Filter = Close == 50;

TelegramAPI_ID = "****************";
TelegramCHAT_ID = "@************"; 

    // Initialize an empty string to accumulate messages
    allMessages = "";
    
    // Loop through all the bars (rows)
    for (i = 0; i < BarCount; i++)
    {
        // Check if the current bar meets the filter criteria
        if (LastValue(Filter[i]))
        {
            // Format the message for the current stock
            message = "Buy : " + Name() + ", Price : " + Close[i] + ", Open : " + Open[i] + ", Low : " + Low[i] + ", Change : " + StrFormat("%.2f", MoM_P[i]) + "%\n";
            
            // Accumulate the message
            allMessages = allMessages + message;

        }
    }

    // Send the accumulated message if there is any
    if (StrLen(allMessages) > 0)
    {
        TelegramAlerts = InternetOpenURL("https://api.telegram.org/bot" + TelegramAPI_ID + "/sendMessage?chat_id=" + TelegramCHAT_ID + "&text=" + allMessages);
        InternetClose(TelegramAlerts);
    }

the result of my exploration like this
Ticker Date/Time Close
