ByInstanceId
Display the specific embedded content instance whose AirshipEmbeddedInfo.instanceId matches instanceId.
If the instance is not currently pending, the placeholder is shown (strict targeting; no substitution is made). This is useful when app-side logic has already selected the desired instance and wants to pin the view to it — for example, across a React Native bridge where a Comparator closure cannot be passed.
Parameters
instanceId
the AirshipEmbeddedInfo.instanceId of the instance to display.
