The implemented D-Bus API should be considered private. It is subject to change in the future.
A given object path can only have one action group exported on it. If this constraint is violated, the export will fail and 0 will be returned (with throws set accordingly).
You can unexport the action group using unexport_action_group with the return value of this function.
The thread default main context is taken at the time of this call. All incoming action activations and state change requests are reported from this context. Any changes on the action group that cause it to emit signals must also come from this same context. Since incoming action activations and state change requests are rather likely to cause changes on the action group, this effectively limits a given action group to being exported from only one main context.
