Grafana 8 Notifications Channels disappear

Hi, I have on a Suse 15-SP2 mounted the Grafana rpm:
grafana-8.0.6-1.x86_64

I have enabled in grafana.ini the [smtp] part.
I have postfix enabled and running

But I am not able to get the Notifications Channels option to appear in the Alert configuration in grafana…

Any ideas?
