Animations only play for one object when imported

Godot Version

4.3

Question

I imported a .blend file into Godot that has multiple mesh objects, each with their own keyframes. When attempting to play the animation in the AnimationPlayer, only one of the meshes plays its animations. How do I make sure that all of the parts animate, rather than just one of them?

Is there only one animation in the AnimationPlayer? I usually see a new animation for each mesh/action combination.
