Using

<?php

$callable = function (Number $number): string {
    $n = $number->number();
    if ($n == 0) {
        return PluralCategory::ZERO;
    }
    if ($n == 1) {
        return PluralCategory::ONE;
    }
    if ($n == 2) {
        return PluralCategory::TWO;
    }
    if ($n == 3) {
        return PluralCategory::FEW;
    }
    if ($n == 4) {
        return PluralCategory::MANY;
    }
    return PluralCategory::OTHER;
};
$allowedCategories = [];

$registry = new \Polyglot\CallablePluralDetector\CallablePluralDetector($callable);
