PHP 8 Warning

[Lievelabels.nl]

I migrated to PHP 8 and see php warnings in my logs. Maybe something that needs to be checked.
PHP Warning: Undefined array key "ppom_id" in /wp-content/plugins/woocommerce-product-addon/classes/form.class.php on line 245

Not sure why this key does not exist at a certain point, but I guess you could fix it by changing line 245 from
$classes[] = "ppom-id-{$meta['ppom_id']}";
to
$classes[] = "ppom-id-" . @$meta['ppom_id'];
