The hibernate button is not working in Gnome 44 (tested on Fedora 38). Probably because something changed in the GTK 4.0.
Error message:
(...) ConfirmDialog (...) has been already disposed - impossible to connect to any signal on it.
I fixed by closing the dialog only after connecting to the closed signal as the object property destroyOnClose is set to true.
