I would not connect a 9V battery to an ESP32 board. I believe they only run on 5V or USB. You will probably fry your board if you do this. I guess you could create a voltage divider circuit to provide 5V from a 9V battery.
I have the Arducam IoTai which, I believe is the same as the Arducam ESP32 PSRAM. I had to purchase a good USB Data Cable to make it work properly.
