Show notification without notification close icon

Here's an example of showing a notification without close button in the notification.

Here's a Typescript example:

const frameworkProvider: IUiEventsFrameworkProvider = await CX_SVC_UI_EVENTS_FRAMEWORK.uiEventsFramework.initialize('MyFirstExtensionID', 'v1');
  let notificationContext: INotificationContext = await frameworkProvider.getNotificationContext('notificationId007'); 
  const requestObject: IShowNotificationRequest = frameworkProvider.requestHelper.createPublishRequest('ShowNotification') as     IShowNotificationRequest;         
requestObject.setTitle('Title');      
requestObject.setClosable(true);                              
notificationContext.publish(requestObject).then((message) => {
      const resp = message as INotificationOperationResponse;           
  });

Here's a JavaScript example:

const frameworkProvider = await CX_SVC_UI_EVENTS_FRAMEWORK.uiEventsFramework.initialize('MyFirstExtensionID', 'v1'); 
let notificationContext = await frameworkProvider.getNotificationContext('notificationId007'); 
const requestObject = frameworkProvider.requestHelper.createPublishRequest('ShowNotification');  
requestObject.setTitle(fieldName);    
requestObject.setClosable(false);  
notificationContext.publish(requestObject).then((response) => { 
// custom code 
}).catch((err) => { 
console.log(err); 
});
