Pose Player by Andrew at Sims 4 Studio

This is a mod that will add the option to play poses and animations in game. It adds an interaction to your sims called Pose By Name. Just click on your sim like you would to do anything else. When you choose the Pose By Name option, you can enter the name of the animation (I have attached a text file below with all EA in-game animation names below) and your sim will do that animation until you cancel the interaction.
