How to replace an animation from the default character? [total beginner]

I have replaced the skeleton and the mesh and also the animations in the running blend space, simply dragging and dropping them on the spots of the blend space. It works, the buddy runs as edited.
But I can’t understand how to replace the other animations. For example, I have a new jump but I can’t find where to set the new one. Dragging and dropping somewhere it doesn’t work.
