P1S button and LEDs

So as you probably know, there is the little hole in the frame for the P1S. I’ve heard that you can connect stuff to the printer with that and some other parts to put stuff in like LEDs and be able to power them. How do I actually go about doing that? Is there stuff like the button on the Bambu store that I need to buy, or something else? Thanks for any help!

There is a USB A port located on the rear of the AP board that can provide 5V. But I will warn you that using the port can cause a variety of issues and it is unprotected so over current situation and shorts will damage the board.
