How to cast const ref to TSharedRef?

I want to expose functions based on this template to blueprint

template<typename OutStructType>
static bool JsonObjectToUStruct(const TSharedRef<FJsonObject>& JsonObject, OutStructType* OutStruct, int64 CheckFlags = 0, int64 SkipFlags = 0, const bool bStrictMode = false, FText* OutFailReason = nullptr)
{
	return JsonObjectToUStruct(JsonObject, OutStructType::StaticStruct(), OutStruct, CheckFlags, SkipFlags, bStrictMode, OutFailReason);
}

however, when I write UFUNCTION declaration like this

UFUNCTION(BlueprintCallable)
bool UPackagesBPLibrary::MakeFPackageFromJsonObj(const FJsonObject& Json, FPackage& OutStruct)

It says const FJsonObject& is not compatiable with TSharedRef. Is there any way to make a cast?
