Expose UObject into actor

[jcastro0x]

I’m trying to expose a UObject variable into an AActor, but in the final steps I can’t finish.
My walkthrough was the next:

I created a UObject class in C++

1. Added a UBoject class within Blueprintable parameter into CLASS macro
2. Exposed inside variables with UPROPERTY macro

UCLASS(Blueprintable)
class SLIMEWAR_API UWeaponBase : public UObject
{
	GENERATED_BODY()
	
private:
	UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = "BaseWeapon", meta=(AllowPrivateAccess="true"))
	float RateShoot;

	UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = "BaseWeapon", meta = (AllowPrivateAccess = "true"))
	float RateShootAmmount;

	...
};

3. I created an AActor class that references the UObject:

UCLASS()
class SLIMEWAR_API AGiverTrigger : public AActor
{
	GENERATED_BODY()

private:
        ...

	UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = "Giver", meta = (AllowPrivateAccess = "true"))
	UWeaponBase* Holi2;

	...

	
};

4. I created a Blueprint class derived from UObject
5. Reference the previously Actor into World, and when I try to link my Blueprint from Content to variable field of Actor, UE can’t do:
   
   

I want create a UObject class to allow the designer can create weapons creating Blueprints that inherits from UWeapon, what can I do?

Thanks!
