As per ChatGpt: ILMessageFilterExtensionConfigurationManager is defined by Apple in the IdentityLookup framework, but with an important caveat about where it is visible. ⸻ Where it’s defined • Framework: IdentityLookup • Platform: iOS • Introduced: iOS 16+

Thanks for confirming! I was looking for a way to confirm if user has enabled third party Text Message Extension Filter. My app is in development / beta testing, and is filtering Unknown Senders Text Messages to classify as Spam, Transactions or Promotions. I'm interested in facilitating the process of enabling text filter app.
