How to make a structuredClone of a Proxy object?

I’m using Vue3 where a lot of the objects are Proxy objects for reactivity. I want to create a deep copy of one of the proxy objects and recently discovered structuredClone.

https://developer.mozilla.org/en-US/docs/Web/API/structuredClone

When I run the following code, I get an error performing a structuredClone on proxyObj:

const obj = {
    name: "Steve",
    age: 50
}
const handler = {}
const proxyObj = new Proxy(obj, {})

console.log(proxyObj)

const objCopy = structuredClone(obj)

console.log(objCopy)

const proxyObjCopy = structuredClone(proxyObj)
console.log(objCopy)

Uncaught DOMException: Failed to execute ‘structuredClone’ on ‘Window’: # could not be cloned.

Is there a way I can clone the proxy object? Is there a way I can dereference it first, copy it, and not lose the reactivity? Any help is appreciated!
