Most of us use Slicer based retraction (reverese extruding commands) but if You want to use Firmware retraction You should have to uncomment the below define in Configuration_adv.h and use the below commands. (not using it myself though)
// Firmware based and LCD controled retract
// M207 and M208 can be used to define parameters for the retraction.
// The retraction can be called by the slicer using G10 and G11
// until then, intended retractions can be detected by moves that only extrude and the direction.
// the moves are than replaced by the firmware controlled ones.
// #define FWRETRACT //ONLY PARTIALLY TESTED
#define MIN_RETRACT 0.1 //minimum extruded mm to accept a automatic gcode retraction attempt
