Do you know JavaScript?
If you do, then you’ll find it pretty easy as Apps Script is essentially JavaScript.
I created a tutorial a while back, which was basically aimed at someone that had never coded. You might find that useful, depending on how familiar you are with Apps Script. If you’ve never touched it, then it might serve as a good primer.
If you take this path and get stuck or need some pointers, feel free to reach out. I do a lot of this.
