How to add animated CUAs

[BigDumbIdiot]

I have a scene that I am working on with a ton of my own CUAs. I've gotten to the point where all is working perfectly aside from the animated assets. I have several low-poly background characters with animations, however I am new to Unity. The models all load fine, But with no animation. They all load frozen in the first frame of the animation. Does anyone know what I am missing. Can't find any tutorials on the topic. I am trying to make constantly animated people assets like the ones in "Crowd Generator" by the creator hazmhox.
