Configure Unattended-upgrades on cyberpanel server


I am finally getting around to use Unattended-Upgrades on my servers, and was surprised to find that Cyberpanel actually configures this, but very litely, and there is no configuration of the email notifications from unattended upgrades.

Since Cyberpanel also installs and activates postfix, it should be possible to make use of Unattended-upgrades.

Are there any docs or hints on how to best configure Unattended-Upgrades on cyberpanel servers

Running Ubunto 20.04lts
