Here reverse geocoder API v6 no longer supported, can Traccar migrate to Here API v7?

I'm using the Here (reverse) geocoder in Traccar and I got a note that the API v6 (using an app id and app code) will no longer be supported after 31 December 2023 and I have to migrate to API v7 (using an apiKey)

Is it possible to adapt the src/main/java/org/traccar/geocoder/HereGeocoder.java to use the Here API v7?
I did some testing on the new Here API and the formatUrl should look like this (not tested in Traccar)

private static String formatUrl(String url, String key, String language) {
    if (url == null) {
           url = "https://revgeocode.search.hereapi.com/v1/revgeocode"
    }
    url += "?types=address&limit=1";
    url += "&at=%f,%f";
    url += "&apiKey=" + key;
    if (language != null) {
           url += "&language=" + language;
    }
    return url;
}

Is the data format the same as before?

Not entirely, but address is still the same structure structure:

Can you please link the announcement? What does it say specifically? We do support an API key with v6 currently.

I got a mail from here.com

Pull request is looking good ;-)
I'll try it as soon as it is in the (preview or) release.
