Unable to get Angular filters working ng-options

Question

So I'm working with Angular version 1.5.7 and receiving an object from the server that looks something like this:

var app = angular.module('myApp', []);function ctrl($scope){
$scope.properties.Consultants = [
    {
        text:"consultant1",
        Group: {Name:"CorporateResource", Disabled:"False"}
    },
    {
        text:"consultant2",
        Group: {Name:"CorporateResource", Disabled:"False"}
    },
    {
        type:"consultant3",
        Group: {Name:"Resource", Disabled:"False"}
    },
    {
        type:"consultant4",
        Group: {Name:"Resource", Disabled:"False"}
    }
];

}

and I need to filter the select list options I'm creating based based on Group.Name to only get values that have Group.Name == "CorporateProject". I've tried many variations of the following but cannot seem to get it to filter properly:

<select ng-model="test" ng-options="c as c.text for c in properties.Consultants| filter:{Group.Name: 'CorporateResource'}"></select>

I keep getting the following js errors thrown:

You had wrong filter, It should look like below

ng-options="c as c.text for c in properties.Consultants 
             | filter: {Group: {Name: 'CorporateResource'}}"
