A message that posts after a mouse accessory connects to the device.
Use the `didConnect` identifier with `NotificationCenter` to listen for
this message.
```
let observation = NotificationCenter.default.addObserver(of: GCMouse.self, for: .didConnect) { message in
let mouse = message.mouse
}
```
Connections of mouse accessories will be reflected in the `mice` array
of the `GCMouse` class when the message posts.
Converts a posted notification into this main actor message type for any observers.
To implement this method in your own `MainActorMessage` conformance, retrieve values from the ``Notification``'s ``Notification/userInfo`` and set them as properties on the message.
- Parameter notification: The posted ``Notification``.
- Returns: The converted `MainActorMessage` or `nil` if conversion is not possible.
