Global menu is not exported when using the flatpak version

Currently using Manjaro with plasma 5.23.3, frameworks 5.88, Qt 5.15.2 and the kernel 5.14.18 on X11. I installed the flatpak version of Gittyup but there's no menu on the global menu at all, for some reason is not being exported. I already checked and it works correctly if:

• i install Gittyup form the AUR using gittyup-git.
• On flatpak version of Gittyup if i remove the global menu from the plasma panel and stop the daemon that exports the menus, then it appears again inside of the window.

Also i already confirmed that this problem doesn't happen with the flatpak version of GitAhead, it works correctly there so this most likely is a regression related to a change done after the fork.

Steps to reproduce:

1. Set up plasma's global menu on a panel so the menus are exported.
2. Install the flatpak version of Gittyup.
3. Run Gittyup, there will not be any way to access the menu because it doesn't appear.

Reproduce the issue on Plasma with the Flatpak build and its global menu panel enabled. Compare the Flatpak behavior with the AUR build and Flatpak GitAhead; done means Gittyup's menu is exported to the panel while the global menu remains enabled.
