Whew, screenshots can be tricky. Let me explain it in simpler terms. First, select your hero by left-clicking. Then, go to the left panel (ObjectPropertiesTree) -> Shared -> Character. In the list that appears, choose the desired character (this will include both the model and the animation). You might need to go a bit further, specifically to Animation, and add extra animations to the right list. The most important one is "cast." However, you should clarify this based on the specific model you're using.
