Given this delegate:  
`public delegate* unmanaged[Cdecl]<lib_kref_Resource, lib_kref_kotlin_Array> listUsers;`

With the next struct definition (generated with ClangSharpPInvokeGenerator):

```auto
typedef struct {
  lib_KNativePtr pinned;
} lib_kref_kotlin_Array;

public unsafe partial struct lib_kref_Resource
{
    public void* pinned;
}

```

And knowing that the kotlin code is like this:

```auto
class Resource {

    class User(
        val id: String,
        val name: String,
        val email: String
    )
    
    fun getUsers(): Array<User> {
        return arrayOf(User("user-id", "user-name", "user-email"))
    }
}

```

How can I convert the pointer? returned by the `listUser` function into a `User[]` array in **C#**?
