Wix Router does not let you access the hash

I have been using the WixRouterRequest in ‘wix-router’ and need to parse the query and hash parameters of a URL before redirecting. When I try to read the hash value, it is empty.

export function my_Router(request) {
    const query = request.query; // works
    const hash = request.hash; // is frickin' empty!
    ...
}

It is in their documentation.

How can I access the hash?!

Also, it is 2024. I’ve seen discussions of this issue dating back till at least 2018. 6 years seems like enough time, right? I will avoid Wix in the future, but for now I’m stuck. Maybe that’s the point. What a unbelievably frustrating product.
