1. Under settings you have to turn off upcoming alarm notifications. 2. Turn on customization service on the clock page and turn on and accept options. For some reason personal information must be shared. 3. Make sure the clock prompt.... is enabled 4. Tap on home button. On an S22 ultra there is text under the settings for alarm notifications explaining it but the developers left the explanation out on the s23 ultra to make it a mystery.
When the lock screen on tap on the time and you can dismiss your alarm in order of soonest to latest. It's kind of strange though as it looks like the alarm is disabled in the app and not dismissed. Samsung clock alarms are clunky...if you don't want to hassle with their developers nonsense use Google clock instead.
