Getting export settings from the main component in a team library

Please excuse me…I’m not a professional developer. I’m trying to write a plugin that is able to find the export settings (set by the user in the app) of a component in a team library when I pull an instance. In the console, I get [object, Object] for mainComponent.exportSettings:

figma.on('selectionchange', async () => {
  const selection = figma.currentPage.selection;
  const instance = selection[0];
  if(instance.type === "INSTANCE" && selection.length === 1){
    const mainComponent = await instance.getMainComponentAsync();
    if(mainComponent){
      console.log("Main component: " + mainComponent.parent?.name);
      console.log("Main component's export settings: " + mainComponent.exportSettings);
      figma.closePlugin();
    }
  }

I’d really appreciate any help, especially if it’s accompanied by a good explanation (since, I’m trying to learn this stuff). Thanks!!!
