Can I running main process from NotificationServiceExtension

Hi all,

I develop an application using remote notification. The notification is encrypted over server so only client can decrypt. Firstly I try to using background task, then I decrypt can make a local notification to user. But this background task sometime missing. And then I try to using NotificationServiceExtension and I check it always receive the remote notification but it not running the main app, and all my business logic is in the main app. So can I running main process from NotificationServiceExtension?

Here is some link I try to do: https://developer.apple.com/documentation/usernotifications/setting_up_a_remote_notification_server/pushing_background_updates_to_your_app https://developer.apple.com/documentation/usernotifications/setting_up_a_remote_notification_server/generating_a_remote_notification https://developer.apple.com/documentation/usernotifications/modifying_content_in_newly_delivered_notifications

Thank you.
