How do you indicate which tools get applied to the chat?

[gordon-vart]

The documentation indicates you pass the tool when you call SendAsync but that method signature appears to have changed.
I am just trying to register the tools that are available during the chat.
Any help would be appreciated! thanks

var chat = new Chat(ollamaApiClient, systemPrompt);
var searchCollectionTool = new SearchCollectionTool();
// register tools?

// callback for tool execution - this is where you can monitor which tools are being called and push updates to the frontend
chat.OnToolCall += async (sender, toolCall) =>
{
// This is your monitoring point
Log.Information($"Executing: {toolCall.Function.Name}");

   // Optional: Push a status update to your React frontend
   await context.Response.WriteAsync($"event: status\ndata: Using tool {toolCall.Function.Name}...\n\n");
   await context.Response.Body.FlushAsync();

};

//
await foreach (var message in chat.SendAsync(prompt))
{

Here is the solution:
var chat = new Chat(ollamaApiClient, systemPrompt);
var searchCollectoddtionTool = new SearchCollectionTool();
var tools = new List
{
new SearchCollectionTool()
};

// callback for tool execution - this is where you can monitor which tools are being called and push updates to the frontend
chat.OnToolCall += async (sender, toolCall) =>
{
// This is your monitoring point
Log.Information($"Executing: {toolCall.Function.Name}");

// Optional: Push a status update to your React frontend
await context.Response.WriteAsync($"event: status\ndata: Using tool {toolCall.Function.Name}...\n\n");
await context.Response.Body.FlushAsync();

};

// 3. Stream the response directly to the HTTP response body
await foreach (var message in chat.SendAsync(prompt, tools))
