Problem with ESP32-cam pir motion connected to Telegram

There it is, @dacho. I've been able to combine the two sketchs, which was surprisingly easy to do. So now I also have access to the video streaming. Here is the code I use :

#include "esp_camera.h"
#include <WiFi.h>
#include <WiFiClientSecure.h>
#include "soc/soc.h"
#include "soc/rtc_cntl_reg.h"
#include "esp_camera.h"
#include <UniversalTelegramBot.h>
#include <ArduinoJson.h>
#include <Wire.h>

#define CAMERA_MODEL_AI_THINKER // Has PSRAM

#include "camera_pins.h"

const char* ssid = "---------";
const char* password = "--------";

String chatId = "-------";

// Initialize Telegram BOT
String BOTtoken = "-------------";

bool sendPhoto = false;

WiFiClientSecure clientTCP;


UniversalTelegramBot bot(BOTtoken, clientTCP);

#define LED 4
#define PIR 2
bool flashState = LOW;

// Motion Sensor
bool motionDetected = false;
bool PirControler = 0;

int botRequestDelay = 1000;   // mean time between scan messages
long lastTimeBotRan;     // last time messages' scan has been done


void startCameraServer();

void handleNewMessages(int numNewMessages);
String sendPhotoTelegram();

// Indicates when motion is detected
static void IRAM_ATTR detectsMovement(void * arg){
  //Serial.println("MOTION DETECTED!!!");
  motionDetected = true;
}

    }

    if (text == "/start"){
      String welcome = "Hi sir, here are the commands I can execute for you :\n";
      welcome += "/Photo : Take a new photo.\n";
      welcome += "/Flash : Toggle flash LED.\n";
      welcome += "/PIRON : Activate your PIR sensor.\n";
      welcome += "/PIROFF : Shut your PIR sensor down.\n";

    }
    /*else {
      bot.sendMessage(chatId, "I don't understand, sorry. Refer to the commands I showed you above.", "");      
    }*/
  }
}

I also tried to add these lines

digitalWrite(LED, HIGH); 
      delay (500);  // It is supposed to turn esp's LED on when motion is detected, but the LED doesn't turn off after that..
  /*else {
      bot.sendMessage(chatId, "I don't understand, sorry. Refer to the commands I showed you above.", "");      
    }*/

But it didn't work as expected, gonna have to find a way to fix that ^^
