I am interested in having multiple Apps Script projects within one Google Sheets Container. These projects all use the same 'mother' spreadsheet, but are unrelated in their functionality.
I've had sheets shared with me that when you click on the "Extensions" within the sheet it takes you to a webpage with a list of Google Apps Script project and asks you to:
"Select a project to open" ...
But I can't figure out how to replicate this.
Can someone tell me how to do this or point me to the right documentation?
Thanks,
Steve
