WorkManager not starting job if application is not launched

Question

I use WorkManager to periodically update widget once in hour. In onEnabled method of AppwidgetProvider I enqueue PeriodicWorkRequest and cancelAllWorkByTag in onDisabled. Here is my code from onEnabled method:

        val constraints = Constraints.Builder()
            .setRequiresBatteryNotLow(true)
            .setRequiredNetworkType(NetworkType.CONNECTED)
            .build()

        val request = PeriodicWorkRequestBuilder<Worker>(1, TimeUnit.HOURS)
            .addTag(workTag)
            .setInputData(workDataOf(EXTRA_WIDGET_TAG to workTag))
            .setConstraints(constraints)
            .build()

        WorkManager.getInstance(context).enqueue(request)

I need to setup widget without app launch, so when I install application I don't open it and setup widget on Home Screen. The problem is that onStartJob method not called without app first launch and I don't understand why. These are logs that I got:

D/Widget: onEnabled

D/WM-Schedulers: Created SystemJobScheduler and enabled SystemJobService
D/WM-ForceStopRunnable: Performing cleanup operations.
D/Widget: onUpdate

D/Widget: onUpdate

And these are logs when app was launched and then widget was setup

I noticed that onStartJob method sometimes can launch without app first launch in 3 minutes, sometimes in 30 minutes. Maybe someone know why it is not launched directly after job was scheduled
