RewardedVideoAd is deprecated. What is the new alternative?

    void loadAds(){         RewardedVideoAd mRewardedVideoAd;         mRewardedVideoAd.loadAd(rewarded_id, new AdRequest.Builder().build());         mRewardedVideoAd = MobileAds.getRewardedVideoAdInstance(this);         mRewardedVideoAd.setRewardedVideoAdListener(new RewardedVideoAdListener() {         @Override         public void onRewardedVideoAdLoaded() {             AppUtils.showLog("REWARDED", "onRewardedVideoAdLoaded");         }         .....         .....     }
