Short intro to the problem: I am trying to create a redirect banner on a multisite website. The problem I am facing is that the multisite has different URL paths for the same page and I don't know how to detect these different URL paths on each Oxygen template. For example website.com/press vs website.de/presse.

Currently, what I've done redirects the user to the same URL on every template using Javascript inside Oxygen.

let redirectUrl = currentUrl.slice(0,34) + redirectCode + currentUrl.slice(37);
    
let redirectLink = document.createElement('a');
redirectLink.setAttribute('href', redirectUrl);

Is there a way to integrate another plugin(if it is can you show me how or at least point me to some resources to learn how to do it) such as Hreflang to detect the corresponding page URL for multisites?
