Is there way to get externalGuids from https://community.plex.tv/api

I am trying to work out a way to sync Plex watch history to Trakt. To do this, i found an API at: https://community.plex.tv/api

I can then use GetWatchHistoryHub in there. I can fetch data such as:

fragment parentFields on MetadataItem {
  id
  guid
  title
  key
  type
}

Does anyone know of a way to also request external guids such as imdb, trakt etc?
