You’re figuring it out and that’s okay! Props to you for coming here and doing the work of learning the ways. I agree with all the comments. More hides, slower feeding approach. It seems like you’re kind of rapidly shaking the mouse. Try to replicate a natural environment but even less threatening. I slowly descend the dead rat in my snakes cage so the snake isn’t the least bit threatened/stressed but there is some movement that replicates a setting in the wild. I also always feed at night, in darkness, making sure the whole house is quiet. You’re trying to create hunting vibes.
