title: Google Apps Script: Display log messages on Google Sheet
body: <p>I am running a fairly long script on a Google Sheet via a custom menu item. Currently, all it says is &quot;Running script&quot; on the sheet. But I would like some informative logger messages to show up on the Sheet itself so that the user knows where in the execution we are.</p>
  <p>Is that possible?</p>
  <p>Just to be clear I do not want the messages to come up in the cells of the sheet as was suggested for this post.</p>
  <p>Thanks!</p>
