Looking for a co-maintainer to help manage this project

If you want to become a co-maintainer (or you are from EEO team), feel free to drop a message here, or [open a request to Flathub](https://github.com/flathub/flathub/issues/new). Also you can help me maintain my [AppImage wrapper](https://github.com/imngkhang/classin-appimage-wrapper) too if you'd like to contribute!
Requirements:
- Using or knowing about Linux and Flatpak
- Knowing about sandbox permissions
- Have free time to maintain this project, accept PRs for new versions or/and review the upstream .deb for new features (especially Wayland and XDG Desktop Portal support, if you found the .deb have new features, you can talk to me by opening an issue)
- For EEO team:
If anyone from EEO sees this, I'd like to hand over or co-manage this wrapper with you (and also, verify this wrapper), and official support for Wayland and XDG Desktop Portal would also better for Linux community.

No source file, test, or entry point is identified. Start by reviewing the linked AppImage wrapper and the Flathub request process, then inspect the upstream .deb for Wayland and XDG Desktop Portal changes. Done means an agreed co-maintainer handoff or ongoing maintenance arrangement, not a defined code change.
