To match against all events from this service, create an event pattern that matches against the following event attribute:
+ `source`: aws.arc-region-switch

```
{
  "source": ["aws.arc-region-switch"]
}
```

To match against specific events, include a `detail-type` attribute specifying an array of event names to match. For example:

```
{
  "source": ["aws.arc-region-switch"],
  "detail-type": ["ARC Region Switch Plan Execution"]
}
```
