Access gpio pins on CrowPanel 1.28inch-HMI ESP32 Rotary Display

Any tips on using extra GPIO pins on this otherwise very neat device?
There's two gpio pins (IO4, IO12) available on the FPC connector, but without a suitable breakout cable i cannot use them. I've read some references about test io pads for the same pins somewhere on the pcb but i can't find any marks. Maybe soldering a wire directly to the FPC connector is the best approach? I only need one gpio pin for my project...
