Passing a javascript function into a c# method as an IntPtr

[LaptopCat]

I am trying to use the BestHTTP library with this example code, but it requires passing in a function as a callback

The constructor method and the callback class look like this:

Here is my current code:

const System = Il2Cpp.domain.assembly("System").image
const Game = Il2Cpp.domain.assembly("Assembly-CSharp").image

/* ... */

const uri = System.class("System.Uri").alloc()
uri.method(".ctor").invoke(Il2Cpp.string("https://google.com"))

const req = Game.class("BestHTTP.HTTPRequest").alloc()
req.method(".ctor").overload("System.Uri", "BestHTTP.OnRequestFinishedDelegate").invoke(uri, /* ??? */)
req.method("Send").invoke()

Sending a request without the overload and callback worked for me, but I need some kind of way to wait until a response is given and using the callback looks the most effective
