Anything more I can do to make notifications arrive exactly on time?

I making a scheduling app where each notification is used as a sort of alarm that tells them it's time to start the next activity. I would like this to be able to happen exactly on time whether the app is open, blurred or killed, however they're usually a few minutes late. I know it's a lot to ask to be so exact, but is there anything more I can do to try to get these notifications to arrive on time? Here's how I'm calling the trigger:

          notifee.createTriggerNotification({
            id,
            title,
            body,
            android: {
              channelId: 'default',
              importance: AndroidImportance.HIGH,
              alarmManager: {
                allowWhileIdle: true,
              }
            },
          }, trigger)

Sorry I just figured out that the alarmManager goes on the trigger not the notification. I'll go test it out and hopefully get the results I'm looking for.
