How to create a template to pass a method from different classes and add it to a Multicast Delegate

Hi,
At the moment i have a Custom GameState that has a Delegate returning void and taking 0 params.

What i am trying to accomplish is to be able to add functions to this delegate that will be fired when it is broadcasted. Same as Dispatchers in blueprints.

I admit i am trying something i’ve never worked with so i might be wrong from the start on how to do it.
Anyway this is the code i am actually trying to use.

DECLARE_DYNAMIC_MULTICAST_DELEGATE(FChangeStateDelegate);

UCLASS()

class MYPROJECT_API AMyGameState : public AGameStateBase
{
	GENERATED_BODY()

public:

	AMyGameState();

	UFUNCTION(BlueprintCallable)
		void EnterSafeState() { machine->ChangeState((int)E_GameState::Safe); };

	UFUNCTION(BlueprintCallable)
		void EnterDangerState() { machine->ChangeState((int)E_GameState::Danger); };

	UFUNCTION(BlueprintCallable)
		void EnterAttackState() { machine->ChangeState((int)E_GameState::UnderAttack); };

//this is the template not working since cannot convert type void(T::*func)() to the type required for addDynamic

        template<typename T>	
	void AddListenerToEnterSafeState(T* obj,void(T::* func)()) {
		OnEnterSafeState.AddDynamic(obj, func);
	};

	//void AddListenerToEnterDangerState(TFunction<void()>* func_to_call);
	//void AddListenerToEnterAttackState(TFunction<void()>* func_to_call);

	
private:
        FChangeStateDelegate OnEnterSafeState;
	FChangeStateDelegate OnEnterDangerState;
	FChangeStateDelegate OnEnterAttackState;
	TSharedPtr<StateMachine> machine = MakeShared<StateMachine>(this);
	TSharedPtr<SafeGameState> safe = MakeShared<SafeGameState>(machine);
	TSharedPtr<DangerGameState> danger = MakeShared<DangerGameState>(machine);
	TSharedPtr<AttackGameState> attack = MakeShared<AttackGameState>(machine);

};

Any help would be really appreciated.

Thanks
