How to get site data (source code) of hosted app

I have ERP Next hosted on Frappe Cloud, and associated with a bench. I have made a few changes to ERP next via the UI e.g. moved left hand menu items around, changed a few doctype screens, changed field names etc etc. Is there any way to download the entire app (source code) ? I know I can access the database but what about all the application python and js files?

Download the database and check it locally.
