Zabbix integration with Grafana OnCall OSS

Hello,

I need to configure Zabbix to send alerts to Grafana OnCall OSS.
Zabbix version: 6.0
Grafana OnCall OSS version: v1.7.1

Following the steps on the Grafana Doc Zabbix | Grafana OnCall documentation, sending a testing alert from Zabbix to Grafana OnCall OSS failed due to “curl: command not found” in zabbix-server image.

I’d much appreciate if you could share your success story for Zabbix integration with Grafana OnCall OSS.

THANK YOU!!!
