CallbackInitializer
Initializer for registering the ReCaptcha Enterprise callback with the Journey SDK.
This class is used by Android's App Startup library to automatically register the ReCaptchaEnterpriseCallback during application initialization. The callback is registered with the name "ReCaptchaEnterpriseCallback" and can be used in Journey flows to handle ReCaptcha Enterprise verification challenges.
The initializer is automatically invoked during app startup, ensuring the callback is available for use in authentication flows.
