   Best practices:

   1. Use built-in Apps Script services where possible – Some services (like SpreadsheetApp) use automatic, less-scary permissions.
   2. Avoid combining unrelated scopes – The more sensitive permissions you request, the more suspicious Google becomes.
   3. Publish as a Google Workspace Add-on – Add-ons go through a streamlined review.
   4. Use service accounts for backend tasks – If users never see an OAuth screen, they never see the warning.
