Can the ADC actually read A0 Battery Voltage on the C6?

I am having trouble reading the battery voltage using Esphome on a Firebeetle ESP32-C6 V1.0 board.  I found a forum posting on the Esphome community that suggests that the 1M ohm resisters used in the on board voltage divider are too high impedance for the ESP32 ADC to read correctly, and that they need to be replaced with 100k ohm resisters.

Has the ability of the onboard ADC to measure ADC_BAT been tested and verified to operate properly?
