If you indeed want a SlowMotion effect thus affect the TimeScale that the game is running, you can use action clip named “Environment/Animate TimeScale” which can be added in an ActionTrack of the Director Group.
Otherwise, if you just want the shot animation only, to be slower, then you really just need to set the keyframes of that shot further apart in time, thus lengthening the shot and making the animation longer.
