I have tried to do it but unfortunately i did not succeed :'(
If somebody has done it before please help!

Here is my code:

#include <ESP8266WiFi.h>
#include <Firebase_ESP_Client.h>
#include <addons/TokenHelper.h>  //Provide the token generation process info.
#include <addons/RTDBHelper.h>   //Provide the RTDB payload printing info and other helper functions.
