Ubuntu 20.04 | App to make live ISO?

Question

I need an application similar to Pinguy Builder (which creates an installable ISO image of your current system) that works on Ubuntu 20.04

If there isn't one, is it possible to downgrade, make the ISO, install, and then reupgrade?

Thanks in advance.

Pinguy Builder Menu Based 5.2.1 dist mode works after making changes in pinguy conf file in the folder /usr/bin. For me it worked of Linux Mint 20 Cinnamon.
