It's the thick brown wire in the bottom wiring compartment
According to your unit's wiring diagram, your C wire should be a brown wire "tail" in the bottom wiring compartment, and while I can't precisely make out what it's wired to right now, it does appear to be present and connected into the existing condenser wiring, which is a good sign that it is indeed the C wire.
