why model.internalModel.coreModel could find method 'setParameterValueById'?

repo site : https://github.com/moushicheng/live-waifu/tree/main/packages/live2d-electron

i print model.internalModel.coreModel

  const model = await Live2DModel.from(model_path, {
    // autoInteract: false, // focus on pointer & response to tapping
  });

  console.log(model.internalModel.coreModel);

At Beginning, i just use 'setParameterValueById' to make model mouth "move",But my model seems to behave differently with #4

model.internalModel.coreModel.setParameterValueById("ParamMouthOpenY", value, 1);

your file type maybe .moc3. but moc file doesn't have setParameterValueById function。so what is the function in .moc file。
