how to know if provider tool is called

[sohailahmad07]

Hi

i am using prism with openai and i am using a websearch tool the open ai provided but look at tool_call or tool_result it empty even the web search tool was called when i can verify from the openai dashboard

here my code

  $generator = Prism::text()
            ->using(Provider::OpenAI, $this->currentModel->model())
            ->withMaxTokens(4000)
            ->withSystemPrompt("You are an assistant")
            ->withMessages($this->relevantConversation())
            ->withProviderTools([
                new ProviderTool('web_search_preview', 'web search preview'),
            ])->asStream();

        $streamData = new StreamData;
      
        foreach ($generator as $chunk) {
            $prismStreamBuilder->handle($streamData, $chunk);
             logger($chunk->toolCalls); // empty
             logger($chunk->toolResults); // empty
            // stream response to livewire
        }
