swift – BGAppRefreshTask not triggering in iOS when app is in background

I’m engaged on an iOS app focusing on iOS 13 and later. I am making an attempt to implement background duties utilizing BGAppRefreshTask, however the process doesn’t appear to set off when the app is within the background.

I’ve arrange the background process in my AppDelegate utilizing BGTaskScheduler and registered the duty with the suitable identifier. I additionally known as submit with a delay, however the process didn’t execute.
