How to avoid re-authorization request for a copied Google Spreadsheet + script

Question

I have a spreadsheet that functions as a template for weekly reports. At this point I copy the undated template sheet using DriveApp to a file that has a date in its name. T

Answer 1

Every time the user calls the function an authorization request is shown. I am trying to avoid that authorization request. Is this possible?

Publishing your script as an add-on would facilitate this; each user would need to authorize the add-on once, and that authorization would remain in effect in any sheet the add-on was used in.
