Why does ESP32-LyraT-Mini V1.2 use an external ADC for the microphone when ADC is already available in Audio Codec?

Why does ESP32-LyraT-Mini V1.2 use an external ADC for the microphone when ADC is already available in Audio Codec?
Kindly refer to ES8311 audio codec datasheet and ESP32-LyraT-Mini V1.2 hardware reference. In the Lyra, an external ADC ES7243 is used to sample the audio signal from the microphone but an equally capable ADC is avaiable in the ES8311 codec ic, why does Espressif use the external ADC?
