Intellisense doesn't work for newly installed az cli extension

[wshamroukh]

When a new az cli extension is added, we don't get IntelliSense for the commands of this new extension. In my case I have just added virtual-wan extension:

az version
{
  "azure-cli": "2.36.0",
  "azure-cli-core": "2.36.0",
  "azure-cli-telemetry": "1.0.6",
  "extensions": {
    "azure-firewall": "0.13.0",
    "front-door": "1.0.16",
    "interactive": "0.4.5",
    "k8s-extension": "1.2.0",
    "virtual-wan": "0.2.11"
  }
}

However in vscode, as you can see, the intellisense doesn't see the newly installed extension and even if i restart vscode:

I have the latest Azure CLI tools installed on vscode as shown below

Would appreciate your help on this one.

Thanks in advance
