Arduino, error sending message to Telegram bot.

[TheBuggia]

Good day to everyone,

currently I'm working on Arduino project for University. In particular, I'm developing an environment which consists in Arduino Uno R4 Wifi, 2 led, a force sensor and a Telegram bot. Basically, the force sensor detects a force and the first led power up; then, when the force is detected longer than 10 sec, the second led light up. In this case, I want to receive a notification from my Telegram bot on my smartphone. The problem is that Arduino doesn't send any message (or Telegram doesn't receive?). Belove the sketch I am using:

#include <WiFiS3.h>
#include <WiFiSSLClient.h>
#include <UniversalTelegramBot.h>

const int pinPressureSensor = A0;
const int pinGreenLED = 11;
const int pinRedLED = 12;

// Wi-Fi credentials
const char* ssid = "xxxxxxxxxxxxxx";
const char* password = "xxxxxxxxx";

// Telegram bot data
#define BOT_TOKEN "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
#define CHAT_ID "xxxxxxxxxxxx"

WiFiClient client;
UniversalTelegramBot bot(BOT_TOKEN, client);

unsigned long startTime = 0;
bool forceDetected = false;

void setup() {
  pinMode(pinGreenLED, OUTPUT);
  pinMode(pinRedLED, OUTPUT);
  digitalWrite(pinGreenLED, LOW);
  digitalWrite(pinRedLED, LOW);
  Serial.begin(9600);

  Serial.println("Connecting to Wi-Fi...");
  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED) {
    delay(1000);
    Serial.println("Connecting to Wi-Fi...");
  }
  Serial.println("Connected to Wi-Fi!");
}

void loop() {
  int sensorValue = analogRead(pinPressureSensor);
  Serial.println(sensorValue);

  if (sensorValue > 1) {
    if (!forceDetected) {
      forceDetected = true;
      startTime = millis();
      digitalWrite(pinGreenLED, HIGH); // Turn on the green LED
    } else {
      if (millis() - startTime >= 10000) {  // After 10 seconds
        digitalWrite(pinGreenLED, LOW);  // Turn off the green LED
        digitalWrite(pinRedLED, HIGH);   // Turn on the red LED
        
        // Send the message to Telegram
Serial.println("Sending message to Telegram...");
bool result = bot.sendMessage(CHAT_ID, "TEST", "");
if (!result) {
            Serial.println("Error sending the message. Check the parameters.");
        }
      }
    }
  } else {
    forceDetected = false;
    digitalWrite(pinGreenLED, LOW);   // Turn off the green LED
    digitalWrite(pinRedLED, LOW);     // Turn off the red LED
  }

  delay(100);  // Stabilize sensor readings
}`  

The code is working regarding the sensor and led, but fails in sending the notification via Telegram. I've already created my bot and start a conversation, I also written some code in Pyhton to better customize it.
Any help in this matter is welcome. I thank you in advance.

Regards
