I can help you create a simple Office Add-in that displays an image of an employee leaving the office. However, I need to clarify that this is not directly related to the provided search results.

To achieve this, we would need to use the office-js library and create a custom add-in. Here's a brief snippet to get you started:

// Import required libraries
const Office = require('@office-js/office-js');
const art = require('art');

// Create an image of an employee leaving the office
const image = art('01_employee_leaving_office.png');

// Define the add-in manifest
Office.addManifest({
  'name': 'Employee Leaving Office',
  'description': 'An Office Add-in that displays an image of an employee leaving the office.',
  'manifestVersion': 2,
  'officeId': '1234567890abcdef',
  'requirement': {
    'minVersion': '1.0'
  },
  'permissions': ['OfficeApp'],
  'main': 'index.js'
});

// Define the add-in's main function
function index() {
  // Create a new Office App instance
  const app = Office.context.app;

  // Display the image in the Office UI
  app.displayImage(image);
}

// Run the add-in's main function
Office.run(index);

Please note that this is just a basic example and you would need to create the 01_employee_leaving_office.png image file and modify the manifest and code according to your specific requirements.
