I know that I can use the Google API executable to have a local script trigger a Google Apps Script. I'm wondering if I can optimize this by eliminating the Apps Script. Are there means by which I can make a message box appear in a Sheet with just a local script? Note: Simply pasting text into the sheet won't work.
For example: Person A has the Sheet open in the browser. Person B submits new data via the command line. This triggers a message box in the sheet for Person A that says "Person B submitted new data."
