SUMMARY If you do connection to activated before doing setActions, slot does not trigger, I verified using dbus-monitor that related dbus signal is emitted but not the lambda slot. See https://invent.kde.org/plasma-mobile/plasma-dialer/-/merge_requests/85 Question is, if is it expected? If so it should be possibly documented?
It should definitely work no matter the order, that said I cannot reproduce in a minimal example
