+Description: >
+  This CloudFormation template creates a set of CloudWatch Logs Insights queries and a corresponding dashboard 
+  for comprehensive AWS Client VPN usage reporting. It provides detailed insights into VPN usage patterns, 
+  connection durations, data transfer volumes, and user activities across different authentication methods 
+  (AD/SAML, Mutual Auth, and Mixed Auth).
