The Flatpak is already packaged and works well. It just needs to be maintained from a person that joins the Inkscape community.
This would allow further improvements like Portal support and making the app official on Flathub.

Keep in mind the Rustdesk flatpak has full access to your machine and isn’t sandboxed
Yes true, thats why it is not published on Flathub.
I will add an override to it that makes sense.
