Native Ads or Styled Ads

I was wondering if it was possible to use native ads from AdMob or if there was a way to stylize the ad component so that it can fit a custom size. I see that the AdMob documentation has support for this but I can’t find this in expo’s version of the AdMob SDK. It would be super cool if someone could show me a way to do this or if there is a workaround by using interstitial ads or anything else. Thanks in advance!
