Make your own Uno no longer detected

My Uno R3 is no longer detected when I plug it into the computer, so I need to reset the MEGA16U2 chip. However all the instructions involve the reset jumper pins, but this board does not have those, instead having a USB C to Serial module, see attached photo. How can I reset the chip??

you may want to clean up those solder joints, some look "cold"
