InterstitialAd.load(this, - mInterstitialAd?.show(this,)

Hello, I updated the sdk, but it keeps giving an error in the "this" part. How can I solve it?

private var mInterstitialAd: InterstitialAd? = null
  fun loadInterstitialAd(applicationContext: Context?) {
      var adRequest = AdRequest.Builder().build()
      InterstitialAd.load(this,"ca-app-pub-3940256099942544/1033173712", adRequest, object : InterstitialAdLoadCallback() {
          override fun onAdFailedToLoad(adError: LoadAdError) {
              mInterstitialAd = null
          }

          override fun onAdLoaded(interstitialAd: InterstitialAd) {
              mInterstitialAd = interstitialAd
          }
      })
      if (mInterstitialAd != null) {
          mInterstitialAd?.show(this,)
      } else {
          Log.d("TA
```G", "The interstitial ad wasn't ready yet.")
      }
