Can't check if a JsValue is a function

[Piripe]

I'm using Jint 4.6.3 with .NET 8.0

I'm trying to check if a JsValue is a function (ICallable) but it doesn't seems possible.
ICallable has been internalized in commit ceee6b2
And there is also a property IsCallable in the JsValue class but also internal

jint/Jint/Native/JsValue.cs

Line 513 in 0cba046

internal virtual bool IsCallable => this is ICallable;

How am I supposed to check if a JsValue is a function/ICallable?
