Is this JSON relevant?

Review ARM-Templates/Add-Event-Subscriptions/azuredeploy.json, especially the role assignment around lines 35-45, and trace whether the sample uses that role elsewhere. Confirm whether the role assignment is required for the sample; document the conclusion and update the sample documentation or template accordingly.

Does the following JSON matter in this sample:

            "type": "Microsoft.Sql/servers/providers/roleAssignments",
            "apiVersion": "2018-09-01-preview",
            "name": "[concat(parameters('sqlServerName'), '/Microsoft.Authorization/', guid(uniqueString(parameters('sqlServerName'))))]",
            "dependsOn": [
                "[resourceId('Microsoft.Web/sites', parameters('functionAppName'))]"
            ],
            "properties": {
                "roleDefinitionId": "[concat('/subscriptions/', subscription().subscriptionId, '/providers/Microsoft.Authorization/roleDefinitions/', '6d8ee4ec-f05a-4a1d-8b00-a9b17e38b437')]",
                "principalId": "[reference(resourceId('Microsoft.Web/sites', parameters('functionAppName')),'2019-08-01', 'Full').identity.principalId]"
            }
	    },

It doesn't seem like the role is needed anywhere.
