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 :

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 ^^
