AppScript to auto-populate Google Docs with Created and Last Updated dates

How to install:

Open the Google Doc where you want this script to run
Select Tools > Script editor menu
Replace the contents of Code.gs with this code and Save
In the left side menu, open Triggers
Create a new trigger which will call function updateFreshness upon event onOpen

In your doc or template, insert {datecreated} and/or {datemodified} placeholders where you want the dates inserted.
Refresh the page to see the dates auto-populated.
On first run, accept permissions to allow the script to run.
Future edits to the page will update the "Last Updated" metadata of the document so that subsequent views of the page will see the revised modified date.
The modified date will be in the format YYYY-MM-DD 📅 and will be highlighted grey to discourage editing. Manually changing the date format or removing the calendar icon will stop automatic updates. The calendar icon links to this repo to provide curious readers with context.
