How to get the memory address of ValueType fields

[SamueleD78]

As in the title, i need to recover the memory address of a field in a struct.
Let's say my code it's this one:

let tmp = Il2Cpp.alloc(MyStructType.valueSize);
const inst = new Il2Cpp.ValueType(tmp, MyStructType.type);

If i console.log(tmp), i have the struct base address.
Now, let's suppose the struct has a field index. I usually recover the value this way:

console.log(inst.field<Il2Cpp.ValueType>("index").value);

But what if want to recover the address that field has in memory?
i tried with console.log(inst.field<Il2Cpp.ValueType>("index").handle) but of course it's wrong.
since it's the first element of the structure, the address should be the same as tmp.
Of course this example it's simple, i know i could just dump tmp. What i need it's to recover the address accessing from the .field() functions.

Is there a way?

Here I calculate the handle.

If the field is static, there isn't a clear way to do so.
