Sleep Coach - How to be notified of sufficient sleep ?

Hello,

I'm owning a Fenix 7 and it will soon see Sleep Coach widget !

However, the whole sleep coach feature is a bit confusing to me.

Ok, the watch will tell you if you need more or less sleep, between 7 and 9 hours, depending of your current stress, HRV etc.

But what is the point of this feature, if there is no "Smart alarm" to wake you up accordingly ?

Is there a way to setup a correct wake up alarm after the sleep coach advice ?
