I debugged it by adding this to UEnhancedPlayerInput::EvaluateInputDelegates() , EnhancedPlayerInput.cpp:558:

       // Trigger bound event delegates
       static TArray<TUniquePtr<FEnhancedInputActionEventBinding>> TriggeredDelegates;
       for (const TUniquePtr<FEnhancedInputActionEventBinding>& Binding : IC->GetActionEventBindings())
       {
           if (Binding->GetAction() && Binding->GetAction()->GetFName().ToString()=="ForwardMovementAction")
           {
               UE_LOG(LogTemp,Log,TEXT("Binding action: %s %s"),*Binding->GetAction()->GetFName().ToString(), *Binding->GetAction()->ActionDescription.ToString());
           }
       ...

This will show all bound input, if you don't see yours then means the player input is disabled or it's not registered/bound.
