They are opening other apps ShareExtension. I think we can’t access other apps ShareExtension and there is no option to programmatically invoke the ShareExtension

Yes, I’ve tried using excludedActivityTypes, but unfortunately it doesn’t fully address my use case. I’m attempting to filter out certain third-party apps and extensions (like WhatsApp or Gmail), which don’t always expose a public UIActivity.ActivityType. Some of these are dynamically loaded or enterprise-distributed, and don’t respond well to being excluded through the standard property.
