Hi @Juyeong_Lee,

It would also be helpful if you could describe what use case you are trying to solve broadly?

One way app can listen to update events is by ticket.propertiesUpdated.

document.onreadystatechange = function init() {
  if (document.readyState == 'interactive') renderApp();

  function renderApp() {
    var onInit = app.initialized();
    onInit.then(getClient).catch(console.error);
  }
};

function getClient(_client) {
  window.client = _client;
  client.events.on('app.activated', onAppActivate);

  function onAppActivate() {
    client.events.on('ticket.propertiesUpdated', onTicketPropUpdate, { intercept: false });

    function onTicketPropUpdate(event) {
      // your business logic
      
      // To allow ticket property to be updated
      event.helper.done();

      // to prevent: event.helper.fail('error message') and {intercept: true} at the call site.
    }
  }
}
