Vonage Laravel verify phone ?

Hello Everyone, I am trying to create a phone verification system with vonage laravel package but i don't want to store the code in my database then send it through sms notification, instead i want to use the verify api provided by the Vonage using the vonage client package installed also i want to publish the vonage config file , i dont know in what provider namespace the config file exists by default. For example, i want to call the verification request to api from some notification or event.
