Beetle ESP32-C6: How to get the battery power level?

Hello,

I just got the Beetle ESP32-C6, and am a newbie to micro-controllers. The wiki states that 'This development board also supports battery voltage monitoring, enabling actions to be taken when the power level is insufficient to ensure the device's continuous operation.'

I assume that on the internal side, the Beetle will take actions to ensure a clean shut down if the battery power becomes insufficient to avoid a hard shut down. Is the monitoring purely internal, or can the power level be read and output to Serial or over BLE as well?

Thanks.
