Yaru Colors Theme Support Request for Flatpak Apps

Project information: Yaru-Colors is a theme project to bring different colors to Ubuntu’s awesome Yaru theme.

Name: Yaru Colors
Homepage: https://github.com/Jannomag/Yaru-Colors/
License: GNU General Public License v3.0
Upstream has been contacted: No

I was looking for the supported themes on Flatpak using the command: flatpak remote-ls flathub | grep org.gtk.Gtk3theme

And, I’d like to see Yaru Colors on that list as well. Could anyone shed some light on it if it’s possible to make it happen?
