Using DS1307 RTC on ESP32 Lora(v2)


Has anyone ever sucessfully used DS1307 RTC (or other models) on Heltec Esp32 V2?
I have tried some libraries and code found online but never had sucess.
I need to use a battery powered RTC in my project in order to mantain proper time.

If anyone can share some solutions on this ill appreciate.
