Request for a UpNote flatpak

Project information: A note-taking application

Name: UpNote
Homepage: https://getupnote.com
License: Proprietary
Upstream has been contacted: Yes

I have contacted UpNote support regarding an official Flatpak, but unfortunately received no response. Since upstream isn’t maintaining one, would the community be open to accepting a third-party/community-maintained Flatpak package for UpNote based on their official Linux distribution packages?
