**Describe the bug** - When the Message Job gets executed (FCMSender sends the message at the specified timestamp), a `MessageStateEvent`: `EXECUTED` must be added. - Currently, when the Message gets added the `ADDED` state event is added, but not when it's executed. - Works for `v2.0.2` and not for `v2.4.0` onwards **Priority** 4 **Difficulty** 4
