[Feature Request]: Expose DelegatingAIFunction.InnerFunction as Public for Custom Middleware Access

[Jimex]

Description

Is it possible to change the access level of DelegatingAIFunction.InnerFunction from protected to public? This would be useful for accessing InnerFunction from a Custom Function Calling Middleware.

Code Sample

var aiFunction = context.Function;
if (aiFunction is DelegatingAIFunction delegatingAIFunction)
{ 
       //Access the function customized property here
     （delegatingAIFunction.InnerFunction as MyAIFunction).CustomContext["ChatId"];
}
