Unity IAP Disable Ads

Hi All,

I have integrated IAP using Unity services into my game, i will have a button on the main menu called "Remove Ads", once they have clicked purchase will process.

My question is, What Function disables Unity Ads?

I need to apply it in this part of my code...

 public PurchaseProcessingResult ProcessPurchase(PurchaseEventArgs args) 
             {
                 // A consumable product has been purchased by this user.
                 if (String.Equals(args.purchasedProduct.definition.id, kProductIDConsumable, StringComparison.Ordinal))
                 {
                     Debug.Log(string.Format("ProcessPurchase: PASS. Product: '{0}'", args.purchasedProduct.definition.id));
                     // The consumable item has been successfully purchased, add 100 coins to the player's in-game score.
                     ScoreManager.score += 100;  //this is the tutorial for IAP integration and will be deleted  
                 }
                 // Or ... a non-consumable product has been purchased by this user.
                 else if (String.Equals(args.purchasedProduct.definition.id, kProductIDNonConsumable, StringComparison.Ordinal))
                 {
                     Debug.Log(string.Format("ProcessPurchase: PASS. Product: '{0}'", args.purchasedProduct.definition.id));
                     // TODO: The non-consumable item has been successfully purchased, grant this item to the player.
    //I need to add the function here to disable the ads as it is a non-consumable purchase
                 }
                 // Or ... a subscription product has been purchased by this user.
                 else if (String.Equals(args.purchasedProduct.definition.id, kProductIDSubscription, StringComparison.Ordinal))
                 {
