EditInlineNew not working in editor

Hello,

I would like to ask if EditInlineNew has some prerequisites to work as e.g. class like this:

UCLASS(editinlinenew, BlueprintType)
    class UTest : public UObject
    {
    	GENERATED_UCLASS_BODY()
    
        UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = "Properties")
    	bool Enabled;
    };

is properly visible as type in editor, but when I create field in blueprint I cannot use “new” to make instance of it (neither in defaults or after placing actor in the scene).

Thank in advance,
cloud
