Luxon interval human readable

Hi I would like to express a luxon interval in a localized human-readable manner (Eg. 9 days, 3 hours).

I have achieved this starting from present moment. With this code:

DateTime.fromISO(value).toRelative({ locale: "es" });

But I cannot achieve the same using neither the Interval o the Duration objects.

This get's the job done. But is not really localization.

    const start = DateTime.fromSQL("2020-06-19 11:14:00");
    const finish = DateTime.fromSQL("2020-06-21 13:11:00");

    const {days, hours, minutes} = Interval
        .fromDateTimes(start, finish, {locale: "es"})
        .toDuration(["days", "hours", "minutes"]).values;
    
    console.log(
        `${days ? days + " días " : ""} ${hours ? hours + " horas" : ""} ${
            minutes ? minutes + " minutos." : ""
        }`
    );

from Luxon interval human readable
