AWS will end support for Amazon Pinpoint on October 30, 2026.

Remarks
Make sure to call this early in your app at the root entry point after configuring Amplify. Initialization runs once per session; subsequent calls are no-ops, so a context passed on a later call will not replace the one captured at first initialization.
Example
```
Amplify.configure(config);
initializeInAppMessaging();
```
