Receiving a PHP deprecation warning related to the filter() method in Rinvex\Country\CountryLoader. The issue occurs due to an implicitly nullable parameter, which needs an explicit nullable type.
Error message:
NOTICE: PHP message: PHP Deprecated: Rinvex\Country\CountryLoader::filter(): Implicitly marking parameter $callback as nullable is deprecated, the explicit nullable type must be used instead in /app/src/php/vendor/rinvex/countries/src/CountryLoader.php on line 125
