Build a reporting history on my google web app

I would like some advise how I should do.

Context: I have a web app google that I build with google app script.my web app takes 16 sheets of my spreadsheet and display on an html page.

My goal now, is to build a history of that reporting (each time we click on a button for instance, its save reports in a new link).

I thought about two options: first: save html content -> create a new html page and insert the html content. ( then loop to the repository to get link).

Second: save spreadsheet each time (but I am not sure how to dynamically get the id of the new spreadsheet).

any advises?
