Using nxfilter on port 8080 instead of 80

[delinuxco]

Greetings,

I am attempting to install nxfilter using CasaOS in Debian 12. Using CasaOS Custom Install screen I am able to install NxFilter docker image with no issue. The problem is that the image is of course set to use Port 80, but CasaOS already uses port 80, so I need to change it to 8080. So I entered the image using docker exec. and tried to edit the nxfilter config file. but there is no editor. So I then tried to install an editor, but to update the system with "apt update".
How can I edit the files in the container?
