Connecting DS3231 to ESP32

[Franky]

Hi Guys

I am trying to interface the DS3231 RTC with ESP32 using the Arduino IDE.
I am unable to find firm information on same.
The uRTCLib library showed promise and I downloaded
uRTCLib-4.3.0.zip which claims to support ESP32.
I have tried to connect it to IO22/SCL and IO21/SDA
on ESP32 without success.
I have used an I2C scanner to check the connection and address
of the DS3231 (0x68). That was fine.
Anyone any idea if this library works and what pins of the ESP32
should be connected to the DS3231 for it to work or maybe there are some issues that I have not considered
Thank you
