Alertmanager and Opsgenie - not see rules

Hello everybody!
I have several containers installed via docker-compose among them Alertmanager.
There are 2 files in the prometheus folder: prometheus.yml alert.rules.
In prometheus.yml there are alert.rules rules connected. But when the node goes down to the Alertmanager, an alert is sent, but a message is sent to the slack instead of the opsgenie.
