You need to create a method “Fire” and add the binding in code (C++ example).

// Called to bind functionality to input
void ACameraDefaultPawn::SetupPlayerInputComponent(UInputComponent* PlayerInputComponent)
{
    Super::SetupPlayerInputComponent(PlayerInputComponent);

    PlayerInputComponent->BindAction("Fire", IE_Pressed, this, &ACameraDefaultPawn::Fire);
}

This is the method binding to. You simply do something like that in the header:

void Fire();

And in the cpp file:

void ACameraDefaultPawn::Fire() {
   // do anything here you want on pressing buttons or similar
}

It’s in the same class where you setup player input component.
