Type safe create url

Hello guys, I need to create a type-safe recovery password email with a token as URL search params.
I would like to have a function that generates that URL like a Link component, but I haven’t found anything.
I created this utility function to solve the problem, but it would be great if the router provided something like this.

import type { LinkProps, RegisteredRouter } from "@tanstack/react-router";

type CreateUrl<TTo extends string> = LinkProps<
    unknown,
    RegisteredRouter,
    string,
    TTo,
    string,
    string
> & {
    to: TTo;
};

export function createUrl<TTo extends string>(props: CreateUrl<TTo>) {
    const domain = process.env.DOMAIN;

    const url = new URL(props.to, domain);
    Object.entries(props.search ?? {}).forEach(([key, value]) => {
        url.searchParams.set(key, value);
    });
    return url.toString();
}
