Ok, I have done a quick check in the meantime. Both a flatpak and an appimage.
Both similar: For the appimage: the plugin goes in ~/.config/GIMP-AppImage/2.10/plug-ins/
However, the plugin expects to find colorwheel_150.png in the regular .config/GIMP/2.10/plug-ins/
Make a new folder structure
(or use your file manager)
and put the files in the appropriate places: https://i.imgur.com/NZQZFu5.jpg
