Assign App Service - Identity to KeyVault in Azure using Pulumi

I create an App Service using "classic" Pulumi.Azure:

        var appservice=new AppService(appserviceName, new AppServiceArgs
        {
            Name = appserviceName,
            Location = _resourceGroup.Location,
            AppServicePlanId = _servicePlan.Id,
            ResourceGroupName = _resourceGroup.Name,
            SiteConfig = new Pulumi.Azure.AppService.Inputs.AppServiceSiteConfigArgs
            {
                DotnetFrameworkVersion = "v5.0",
                ScmType = "None",
            },
            Tags = { { "environemnt", "dev" } },
            Logs = new AppServiceLogsArgs
            {
                HttpLogs = new AppServiceLogsHttpLogsArgs
                {
                    FileSystem = new AppServiceLogsHttpLogsFileSystemArgs { RetentionInDays = 14, RetentionInMb = 35 }
                }
            }
            ,
            AppSettings = appSettings
        });

I also create a keyvault:

  var currentConfig=Output.Create(GetClientConfig.InvokeAsync());
            var keyVault = new KeyVault(vaultname, new KeyVaultArgs
            {
                Name = vaultname,
                Location = _resourceGroup.Location,
                ResourceGroupName = _resourceGroup.Name,
                TenantId = currentConfig.Apply(q => q.TenantId),
                SkuName="standard"
                , AccessPolicies=
                {
                     new Pulumi.Azure.KeyVault.Inputs.KeyVaultAccessPolicyArgs
                     {
                         TenantId=currentConfig.Apply(q=>q.TenantId),
                         ObjectId=currentConfig.Apply(q=>q.ObjectId),
                          KeyPermissions={"get", "create", "list"},
                          SecretPermissions={"set","get","delete","purge","recover", "list"}
                     }
                }
            });

Both work as expected. KeyVault and App Service are being created and accessable by me. Now I need that the App Service also can access the KeyVault.

But when adding a new Access Policy I am stuck at the ObjectId. The App Service does not seem to have a valid object id I can assign to the vault. When checking the service on Azure Portal I also see the Identy is missing: Identity in Azure

So what has to be done as pulumi code that would achieve the same thing as clicking onto "On" in Azure and retrieve the ObjectId afterwards?

You need to set the following property on AppService to enable the managed identity:

Identity = new AppServiceIdentityArgs {Type = "SystemAssigned"},

This example illustrates the end-to-end implementation: https://github.com/pulumi/examples/blob/327afe30ce820901f210ed2a01da408071598ed6/azure-cs-msi-keyvault-rbac/AppStack.cs#L128
