Flatpak GNOME version

[MenonRB]

Have installed the Flatpak version, and it works well. Thank you.

When doing a command-line update, the following error comes up:

Info: runtime org.gnome.Platform branch 46 is end-of-life, with reason:
The GNOME 46 runtime is no longer supported as of April 17, 2025. Please ask your application developer to migrate to a supported platform.
Info: applications using this runtime:
io.github.manisandro.gImageReader

Does this need to be updated within the flatpak version itself or can a user do something to change the GNOME version.

Thanks
