Ok, you probably need to create it then. Here is what mine looks like https://github.com/jscancella/myKlipperFiles/blob/main/vcore3-webcam.txt

Just to note, if you are on the latest RatOS then it uses crowsnest.conf

See Maverik's comment above. crowsnest.conf goes next to your printer.cfg (same directory).
