I2S with built-in ADC to capture stereo

Hi, I would like to use I2S with built-in ADC to capture stereo audio. I have read the ESP-IDF, seems only the first built-in ADC can be used in I2S. Am I wrong?
Thank you in advance!

Yes, only the first ADC unit is available via the I2S driver, you can refer to the dedicate ADC driver for the full support of ADC continuous mode
