Hi, We are trying Signoz onprem. Unable to create Alert channel with Mail. " Configure Alertmanager The following environment variables must be set for Alertmanager to send emails: ALERTMANAGER_SMTP_FROM: The email address to which alerts are sent. ALERTMANAGER_SMTP_HOST: SMTP host received from your email provider. ALERTMANAGER_SMTP_PORT: SMTP port received from your email provider. ALERTMANAGER_SMTP_AUTH_USERNAME: SMTP user received from your email provider. ALERTMANAGER_SMTP_AUTH_PASSWORD: SMTP password received from your email provider. Test Configuration: Click the Test button to send a test alert to the configured email addresses. This verifies that SigNoz can communicate with your email provider. " It is said that you can set it this way in the document. I enter alertmanager.yml but I still get an error. Could I be doing it wrong?

just set the env in as mentioned in https://signoz.io/docs/alerts-management/notification-channel/email/#configuring-alertmanager
