ADC1: 6 channels or 8 channels

Using ESP32 (not ESP32s) ADC1 is supposed to have 8 channels. ESP32 datasheet is very clear on 6 of the channels. However, I can not find the GPIO pins that connect to ADC1_CH1 and ADC1_CH2. Any help will be appreciated.

My datasheet has:
Name No. Type Function
SENSOR_CAPP 6 I GPIO37, ADC1_CH1, RTC_GPIO1
SENSOR_CAPN 7 I GPIO38, ADC1_CH2, RTC_GPIO2
But it will depend on what other features you are using.
You may need to reroute other desired features to other pins in order to clear 6&7
