How to access router in beforeLoad()?

[Albert-Gao]

for this doc:
https://tanstack.com/router/latest/docs/framework/react/guide/authenticated-routes#redirecting

it says:

Since we'll be replacing the entire URL with what it was, router.history.push is better suited for this than router.navigate:

> router.history.push(search.redirect)

But here is the problem, we are in the beforeLoad(), and I can NOT find any router from the ctx parameter, so how do we do this, write this as an useEffect in the component? so we can access the router via useRouter?

Thanks :)
