S10+ Alarm Notification

[Android Central Question]

I just got a Galaxy S10+ (my first Samsung phone), and was wondering if anyone knew how to change the amount of time before an alarm the notification pops up with the pre-installed Clock app. By that I mean the notification that says 'Upcoming Alarm' and gives a button to 'Dismiss'. It only comes up 5 mins before the alarm, which I think you will agree is totally useless. The 'Google Clock' app fixes this problem but doesn't have any widgets that go with it, and I use the widgets for everything (I use alarms a lot for work). Thanks.
