I want to reverse the filament detection sensor contact #15

As a filament detection sensor, the proximity sensor was purchased as an NPN NO type and the filament detection was reversed. Is there any way to use this sensor now by modifying the firmware? If so, I'd appreciate it if you could tell me where to fix it.

Read the Config.h This a setting that is already there

define FILAMENT_SENSOR_INVERTING true // Set to true to invert the logic of the filament_Sensor.
