Detect dark theme for GTK based DEs like elementary OS

[Alecaddd]

I'd like to propose the addition of the --system-talk-name=org.freedesktop.Accounts argument to enable the detection of the Dark/Light variation on GTK based distros that follow the FreeDesktop specifications.

Thx, can you confirm without this change theme detection doesn't work and with it it does?

Build 69262 successful
To test this build, install it from the testing repository:

flatpak install --user https://dl.flathub.org/build-repo/67099/org.mozilla.Thunderbird.flatpakref

From the info I gathered gnome doesn't need this permission alongside latest elementary or even kde.

Confirming that with the current flatpak stable release, theme detection doesn't work in elementary OS.

Testing the build now.

Nope, nevermind.
That argument doesn't do anything and the application doesn't follow the OS theme variation.
This seems to be an issue with elementary OS since in Ubuntu it works even without the argument.
Apologies for the noise.
