How to use the paraview-glance/src/config.Proxy function in paraview-glance

export function createViewer(container, proxyConfig = null) {
  const proxyConfiguration = proxyConfig || activeProxyConfig || Config.Proxy;
  const proxyManager = vtkProxyManager.newInstance({ proxyConfiguration });

  const store = createStore(proxyManager);

  // subscription won't be unsubscribed b/c we currently
  // don't have a way to destroy a viewer
  registerProxyManagerHooks(proxyManager, store);

  /* eslint-disable no-new */
  new Vue({
    el: container,
    components: { App },
    store,
    vuetify: new Vuetify(),
    template: '',
  });

function createStore(proxyManager = null) {
  let pxm = proxyManager;
  if (!proxyManager) {
    pxm = vtkProxyManager.newInstance({
      proxyConfiguration: Config.Proxy,
    });
  }

  return new Vuex.Store({
    state: {
      proxyManager: pxm,
      route: 'landing', // valid values: landing, app
      savingStateName: null,
      loadingState: false,
      panels: {},
    },
    modules: getModuleDefinitions(),
    mutations: {
      SHOW_LANDING(state) {
        state.route = 'landing';
      },
