Python: Can the CodeInterpreterTool return an image file?

I'm able to run the CodeInterpreter, send it some CSV to analyze and have it generate a graph, but I can't find any way to retrieve the image. AgentResponse seems to only return the text, including the generated Python source code. I've found some old docs about AF returning Artifacts and ToolRestultContent, but they all appear to be out of date. None of the Messages or their related Content seem to contain any binary data. The text result shows a path to the generated file in the Linux sandbox. Thanks in advance.

@MikeYeager which chat client and model etc are you using with this?

@eavanvalkenburg AzureOpenAIClient() with o4-mini.

        var codeInterpreterContaier = new CodeInterpreterToolContainer(
             CodeInterpreterToolContainerConfiguration.CreateAutomaticContainerConfiguration());

        var tool = new CodeInterpreterTool(codeInterpreterContaier);

        AIAgent agent = new AzureOpenAIClient(new Uri(_azureOpenAiEndpoint), new ApiKeyCredential(_azureOpenAiApiKey))
            .GetResponsesClient()
            .AsAIAgent(model: "o4-mini",
                        instructions: "You are a helpful assistant that can write and execute Python code. When the user provides a file or asks for computation,\r\n    decide whether to use the Code Interpreter.\r\n    Use Python for data analysis, statistics, and charting.\r\n    Always explain your reasoning and results.",
                        tools: [AIFunctionFactory.Create(CSVReaderTool.ReadLocalFile),
                        AIFunctionFactory.Create(JPGWriterTool.WriteLocalFile),
                            tool.AsAITool()],
                        name: "PythonCodeInterpreterAgent");

        AgentRunOptions options = new() { AllowBackgroundResponses = true };

        AgentSession session = await agent.CreateSessionAsync();

        AgentResponse response = await agent.RunAsync("Read a designated local CSV file into a string and show me a graph of the difference between the daily high an low temperatures for the period. Download the results as a JPG imgage, download it, and store it locally.", session, options);

I've provided a function to read the CVS file from a local drive, which works as expected, and a function to save the JPG to the local drive.
