Need help locating SWDIO, SWCLK, GND, and 3.3V pins on Creality Ender-3 V3 SE board to connect ST-Link V2 for Klipper flashing

Hi, I have a Creality Ender-3 V3 SE and want to flash Klipper. I need to connect an ST-Link V2 (or USBasp) to the mainboard and locate pins SWDIO, SWCLK, GND, 3.3V. Photos of the board (front/back) are attached. Can someone help identify these pins?
