title: A way to show HTML-based dialog to everyone
body: <p>Is there a way to show a dialog with .showModalDialog() based on HTML template HtmlService.createTemplateFromFile() to everyone, not only editors of the spreadsheet?</p>
  
  <p>I have <a href="https://docs.google.com/spreadsheets/d/1zjSYxw8Q8rWA5D6mupFwv4oN76-D8bIvV2kHSTd8s70/edit#gid=1616508651" rel="nofollow">a spreadsheet</a> where I'd like to present data from in HTML prepared template but it shows only to editors. Is this a well-known issue?</p>
