+2. To install the MetalLB Arc extension, obtain the AppID of the MetalLB extension resource provider, and then run the extension create command. You must run the following commands once per Arc Kubernetes cluster.
 
 Obtain the Application ID of the Arc extension by running [az ad sp list](/cli/azure/ad/sp?view=azure-cli-latest#az-ad-sp-list). In order to run the following command, you must be a `user` member of your Azure tenant. For more information about user and guest membership, see [default user permissions in Microsoft Entra ID](/entra/fundamentals/users-default-permissions).
 
 ```azurecli
-$appID = az ad sp list --filter "appId eq '087fca6e-4606-4d41-b3f6-5ebdf75b8b4c'" --query "[].servicePrincipalNames" --output tsv
