I have written Apps Script code for Google Spreadsheet to serve my personal purpose. I learnt from Google site that custom made things to show up in Google Spreadsheets mobile app it has to be published as add-on. Do we have to go only in this route to get my custom made functionality in google spreadsheet mobile app?
EDIT: I have to clarify my question, actually I have created custom menus to call custom functions in google spreadsheet. These custom menus are not shown in the google spreadsheet mobile app. This is my requirement.
Apology for not asking question clearly.
