How to integrate OpenAI ResponseTool.CreateFileSearchTool?

[flintlouis]

OpenAI added the new ResponseClient which can be transformed to an IChatClient also, with everything working the same.
They also added a pre made filesearch tool ResponseTool fileSearchTool = ResponseTool.CreateFileSearchTool([vId]);
I like the pipeline I built with Microsoft.Extensions.AI and want to keep it as abstract as possible.

I was wondering is there a way to add the ResponseTool from open AI to the ChatOptions.Tools?

There will be, we just haven't added it yet.

As noted in one of those issues, the intent is also to have an escape hatch so that future such hosted tools can be used directly if you know which provider you're talking to and want to just add it directly into the tools collection.
