Goal
I want to secure the original source code.
What I did
So I made two libraries connected together as replied here by Tanaike: How to make Google Apps Script library always serve the latest version
the script B, which has the original source code. the script A, which calls the script B as library.
Finally, the script A is called from the script C. Access of The script B, A is anyone with link, so the script C can call the both scripts without access errors.
In this point the user of the script C knows the url of the script B, because the user knows the project ID. But when the user check the script B, the user only finds the original source code is not there, only knows a library is connected. **The user cannot find the project ID of the script A. **
Question
Can the user or anyone on the web search for the script B because it is open to public? Or will it be omitted from Google Search Engine, so that the script A is secured?
