How to select an external 32K crystal in ESP32-S2

Hello, can someone tell me what I need to do, to use external 32KHz crystal in ESP32-S2 and Arduino IDE. The crystal is good, the code written in Visual Studio Code works fine on the external crystal after I selected it in the configuration.

How can I recreate this using Arduino IDE?

So far I've only managed to start an external resonator in the Arduino IDE (as I can see on the oscilloscope) but the RTC does not use it, instead it uses the 8MD256 source I think because the RTC is rushing as if the source had ~33100Hz.

Thank you in advance for your response, have a nice day!
