Facial animations

Hey all. Does anyone here know how to get a hold of a decent pack of facial animations? My player character currently looks dead-eyed. Ideally, I’d at least like him to be able to blink. Can’t find anything on the asset store or Mixamo. Any help would be appreciated.

Hugely appreciated. Thanks.
