Cron container is gone. How to restart?

I use EasyEngine v4 and my cron container (see https://easyengine.io/handbook/cron/) is gone. When I run docker ps -a it is neither in the running nor in the stopped containers.

How can I restart the container (or where can I find the docker-compose.yml which defines the container configuration)?

I had already tried to use ee service enable cron, but it just has shown “Error: Unable to find global EasyEngine service cron!”.

Thanks!
