Beetle ESP32-C6 pin 4

This I got from the info page on DFRobot site:

From this I read that pin 4 could work as a GPIO. So I included it in my project, among a bunch of other pins, like 19 and 20 for I2C, which works fine. But this pin 4 seems to do some important stuff and should probably not be touched. I tried to use it for reading a button, activating a PULL_UP resistor and having a push button connecting the pin to GND. It didn't behave as expected, so I read more about the ESP32-C6 itself in the Datasheet. I got this:

So by pulling down the pin with my button, I actually power off the chip, right? Did I miss that on the info page on DFRobot site? Or was it never mentioned?
