About including JS libraries and about reading external files (File System)

[QuetzalcoutlDev]

Hello, I have a question about inserting JS libraries in GDevelop.

I haven't seen a detailed explanation of how to include one, or maybe I'm missing some detail that I haven't seen.

And the other question I have is about making GDevelop read external files, such as a .txt file.

I have questions about this. Is it possible?

And second, is it possible without sacrificing Android compatibility or making the engine “insecure”?

Of course, there are the “file system” actions, but I read that it's only for Windows, Linux, and Mac.

If I change my question, perhaps it would be, is it possible to make GDevelop read external files without having to modify them? That is, read them as read-only, because in the more than 3 years that I've been using GDevelop, I haven't seen the “File system” action change.

Maybe I'm not explaining myself well, I hope I've made myself clear, if not, I apologize.
