setScalar does not seem to affect fbx model size

Questions

I have a 3d model I would like to scale, however after I scale it using setScalar(), its size doesn’t seem to change in the camera. Why does this happen?

 async function loadFbxSync(path) {
  return new Promise(function (resolve) {
    fbxLoader.load(path, function (fbx) {
      resolve(fbx);
    });
  });
};

const rawCharacterModel = await loadFbxSync("soldier.fbx");
const characterModel = rawCharacterModel.clone();
characterModel.scale.setScalar(0.01);
scene.add(characterModel);
