Reset PIN for ESP32-CAM (AiThinker)

Hey there,
i struggle understanding the Reset-PIN and the required configuration. I am using an AiThinker ESP32-Cam and configured it according to the docs. I use it in a solar project which sometimes provide sunstable voltage during initializing. Therefore i need to be able to power-down the cam (if not needed) or reset the cam (if the initialization fails)

I came across this post already (Esp32 cam on/off by power_down_pin: GPIO32?). It seems the power-down scenario is described here.

Does someone of you managed it to reset the ESP32-Cam with a button / switch?

Did you find the solution?? If you did, pls tell me too.
