I am trying to access the vastAdId property that is inside the AdManager for MediaTailor streams. I can't seem to find a way of getting this data as there is no function to directly access it. I can see that there are functions to access similar data in the same object, e.g getAdId, getTitle etc, but there doesn't seem like there's a direct way to get the vastAdId in the same way (also inside getAdManager() I can see the id buried several layers down under minified functions.)

I've tried to access it by logging something similar to what's done in here - https://shaka-player-demo.appspot.com/docs/api/lib_ads_media_tailor_ad.js.html#line285 (for example trying return this.ad_.vastAdId;) but this does not work.

Is there anything that exposes this data and has an easier way to access this data?
