 ### Listener SSL certificates 
 
 This section allows you to list all the SSL certificate objects that are present on your application gateway. This view is equivalent of running PowerShell command `Get-AzApplicationGatewaySslCertificate -ApplicationGateway $AppGW` or CLI command `az network application-gateway ssl-cert list --gateway-name --resource-group`.
