Seeking Guidance: Understanding the Usage of IA_MOVE in Unreal Engine Version 5.3? Magic?

I’ve thoroughly examined all the EnhancedInputAction calls, and it also seems that the tag InputTag.Move isn’t being referenced anywhere. I’m feeling completely lost here. Any assistance would be greatly appreciated.

EDIT
The tag was initially defined in LyraGame\LyraGameplayTags.cpp and subsequently bound in LyraGame\Character\LyraHeroComponent.cpp. Line 286 of LyraHeroComponent.cpp
the binding:
LyraIC->BindNativeAction(InputConfig, LyraGameplayTags::InputTag_Move,ETriggerEvent::Triggered, this, &ThisClass::Input_Move, /bLogIfNotFound=/ false);
