title: How to delete a google apps script service
body: <p>I tried a particular app script (Gmail Meter) by adding it to a spreadsheet. Even though I think I deleted the spreadsheet (manually checked through past spreadsheets), it did not quite delete the service and I keep getting alerts (I revoked its permissions somewhere and I keep getting notifications that the service requires authorization).</p>
  
  <p>How do I delete this service permanently?</p>
