ESP32 Audio Kit V2.2 A402 Project Voice Assistant

Hi, I bought the Esp32 Audio Kit board thinking that it will be the motherboard of my voice assistant. But I have a little problem with selecting the code for this board so that the microphone and output to the speakers work. Does anyone know about this? I would like to connect 1 microphone, now I don’t know if it is better to do it via JACK or to desolder one microphone and solder a new one into the 1 MIC input. And the speaker output, if possible, I would like to do it after the JACK output, but if the JACK output is not supported, 2 speaker sockets will be enough, I will modify it.
