How can I play my characters animation in the outliner?

I’m new to Unreal Engine and I’m guessing this must be simple, but after researching, I cannot figure out how people are playing characters facial animations inside the outliner. I know how to play my characters facial animation by clicking on the head from the content menu, but not in the outliner.

When I press “Play” from the outliner, it plays my level as though it were a game, but I want this to play my characters facial animation so I can see the groom hair moving with the face. How can I do this?
