Exporting from App Lab to integrate with Google Apps Script

I have created some very useful tools for teachers using App Lab (i.e. a random dice roller, random spinners etc). I would like to try and incorporate these tools into Google Slides. I’ve been trying to see if I can use Google Apps Script to either create an Add-on for Google Slides or a menu option that would run my code. My question is, does anyone have experience with Google Apps script that can help? I imagine that I’d need to export my project from App Lab to get the html, css and java files and somehow incorporate them into Google Apps script.
Any advice would be greatly appreciated.

Hmm, this is an interesting question and I don’t know the answer - but if you figure it out I’d love to be able to do this too!

I think my first step would be to try to export a project. You can do this by clicking “share” then “advanced options” which will expand your window to look like this:

Once you’ve got the zipped file I’m not much help. Time for a crash course in Google Apps script!
