How to handle Fedora upgrades in Podman containers?

I am on Kinoite so I use Distrobox/Toolbox for many big apps like QGIS or RStudio (using iucars COPR)

I am confused how to upgrade the versions or even the images. Previously I just handled the Containers like normal Distros, using their package managers for updates. distrobox-upgrade does exactly that, entering every container and using the package manager.

But now again another version release comes, what do I do with my registry.fedoraproject.org/fedora-toolbox:38 container? Can I upgrade it using Podman?

I am already considering using Rawhide Containers to avoid that, but I suppose that is not the best idea.
