How to get custom data into a tool function call?

[MarkoBL]

How can we get custom data into tool function call? Real world use: In the tool function, I need to be able to identify the user or send something over the connected websocket to the client, independent from the output.

Just a simple example with an overloaded InvokeFunctionAsync call.

        [Function("Get the current temperature for the current user location.")]
        public static Task<string> GetCurrentWeatherAsync(Context context, [FunctionParameter("The units the user has requested temperature in. Typically this is based on the users location.")] WeatherUnit unit)
        {
         var userid = context.userid;
         var userlocation = whatever.getlocation(userid)
         return temp.bylocation(userlocation, unit)
        }

         var functionResult = await toolCall.InvokeFunctionAsync(userContext);

Or maybe make the first argument the ToolCall object (always/or check) . And use it like this:

         // store the context somewhere else
         Context.SetContext(toolCall.ToolCallId, myContext);
         // or add a custom property to the toolCall
         toolCall.WhatEver = myContext;
         var functionResult = await toolCall.InvokeFunctionAsync();

        [Function("Get the current temperature for the current user location.")]
        public static Task<string> GetCurrentWeatherAsync(ToolCall toolCall, [FunctionParameter("The units the user has requested temperature in. Typically this is based on the users location.")] WeatherUnit unit)
        {
            // first
            var myContext = Context.GetContext(toolCall.ToolCallId);
            // second
            var myContext = (Context)toolCall.WhatEver;
        }
