Following deprecation warnings popped up during package:discover operation in a Laravel project:

[2025-01-04 20:19:26] local.WARNING: Pusher\Pusher::__construct(): Implicitly marking parameter $client as nullable is deprecated, the explicit nullable type must be used instead in /var/www/vendor/pusher/pusher-php-server/src/Pusher.php on line 63
