change instanceOf to is_subclass_of

[christmex]

change instanceOf to is_subclass_of, instanceOf return false even tho we implement the function in our model. but when I change it to is_subclass_of it works

here is my class I did implement it, but like I show you, the image error, it doesn't work if use instaceOf

class User extends Authenticatable implements FilamentUser, HasAllowedFields, HasAllowedSorts, HasAllowedFilters

// Which fields can be used to filter the results through the query string
    public static function getAllowedFilters(): array
    {
        return ['name'];
    }

thank you
