Use a standalone script
Standalone scripts are often utility scripts, such as a script that searches Drive for files named "untitled" so you can delete them.
A standalone script can also be deployed as a web app or set up to run automatically from an installable trigger.
Apps Script standalone scripts are suitable for lightweight add-on development for you, your team, or your organization. For larger projects, consider building a Google Workspace add-on on a different runtime environment.
