This even provides the advantage of being able to see console output when a Task Pane or Office JS Dialog loads, where before you had to open it first, then launch DevTools, then refresh the page to reload the add-in again. However, if you close DevTools when you launch the New Outlook with this command, you will have to run the command again to bring back DevTools - but it will start a second instance of the New Outlook.
Hope this helps!
