I am using Laravel 11.

I would like to add a rule after the validation.

Today I have this situation :

public function rules(): array
    {
        return [
            'group_id' => 'required|uuid|exists:groups,id',
            'user_id' => [
                'required', 'uuid',
                Rule::exists('users', 'id')->where(function (Builder $query) {
                    return $query->whereIn('role_id', ['STUDENT', 'TEACHER', 'ADMIN']);
                }),
            ],.......

I added an after method :

     public function after(): array
        {
    
            return [
                function (Validator $validator) {
.......

My wish is how to execute this after method only if all the previous rules passed ?
