It would be great if you could provide a flatpak package of this app to https://registry.fedoraproject.org/.

Especially for users of Fedora Silverblue https://silverblue.fedoraproject.org/ this then allows a seamless installation and upgrades without rebooting the system (just restarting the application).

Additionally, flatpaks can of course be installed on any distro, so also non-Fedora users could use it too.

I know this app is available on Flathub as a flatpak, but I still prefer Fedora's package testing/QA etc., that's why I'd also like to have a version on https://registry.fedoraproject.org/. Also Flathub is a third-party source from the Fedora users/projects viewpoint, so I guess some users would not like to use third-party app sources.
However, the fact that it is on Flathub should make it easier for you to implement this, because you can have a look on how they do it. (Not that you need to do everything in the same way, but it proves it is possible to package as a flatpak, at least.)

This is really a basic GNOME application, so not being able to use this on Silverblue (without rpm-ostree layering or "inofficial" Flathub as a source) is quite bad.
