How can i connect from temporal server to ES using https protocol ?

Configured master credentials in ES for temporal server to connect to it.  
curl --fail --user “username”:“password” http://{opensearch\_instance\_endpoint}:443

Open Search allows only secure connection on port 443. But temporal is connecting using http protocol. any idea , how can i change it to use https ?

Have you tried setting the “scheme” param to “https”? [temporal/config\_template.yaml at master · temporalio/temporal · GitHub](https://github.com/temporalio/temporal/blob/master/docker/config_template.yaml#L182)
