Scheduling a native alarm/timer

I’m working on a cookbook app where the core value proposition should be alarms/timers for each ingredient/step.

I’ve probably got 90% of the way done, and suddenly I’m realizing, I’m not sure if it’s possible to schedule an alarm/timer on the device from Ionic.

Local notifications could work, I’ve been experimenting with it, but it’s just a notification; I haven’t found a way to keep them notifying continuously until dismissed. (Is there a way?)

Push notifications might work, but I get the feeling that would be a lot of non-ideal overhead.

Is there any way, with Cordova / Capacitor / etc, to schedule an alarm/timer in the same way a normal user would?

Hello Sir,
did you find any solution for this?
