I have some doubts and inconsistency in the documentation related to M5stick C push button mapping

In the documentation we have
https://docs.m5stack.com/#/en/core/m5stickc

BUTTON A GPIO 37
BUTTON B GPIO 39

If I check the schematic I don’t see the mapping at all
https://github.com/m5stack/M5-Schematic/tree/master/Core

In the ESP Core schema there are no GPIO37 mapping on ESP32
In the UART schema I found two buttons: one connected to GPIO 35 , the other one to EN net so PIN 5 of IP5306 / PIN3 of ESP32

Really confuse

More over the left button, the power ON/OFF button where is connected is the one connected to IP5306 ?

Can someone provide clarification and provide a correct schematic ?
