How to identify and uninstall packages installed as dependencies during custom backport creation?

I'm using the method on the link below to create a custom Debian backport, ex. for packages that are otherwise not yet backported but exist in testing branch: https://wiki.debian.org/SimpleBackportCreation Now I would like to undo installed backport package however simply running sudo apt purge is not enough because I see some packages have been installed that survive the purge. (I see them in application menu and can run them) Question is how to identify all the extra packages that were installed to be able to purge them as well? I still have build directory that was used to build the backport. If I run sudo less /var/log/apt/history.log the log will show only the backport but will not show those extra packages that were installed. The specific package that I currently want to purge as well as dependencies is crow-translate: https://packages.debian.org/trixie/crow-translate The extra packages in this specific case that I see in application menu are: - QT 5 Assistant - QT 5 Designer - QT 5 Linguist But I believe there are more that are not visible in application menu.
