javascript - angularjs filter based on matching values in nested array

Here is my code. Please run the script to see how it works :

var app = angular.module('myApp', []);

app.controller('listdata', function($scope, $http) {
var data = [{
    "name": "John",
    "queue": [{
        "number": "456",
        "status": "Unavailable"
    },
    {
        "number": "111",
        "status": "Unavailable"
    },
    {
        "number": "201",
        "status": "Paused"
    }],
    "phone": "7411173737"
},
{
    "name": "George",
    "queue": [{
        "number": "111",
        "status": "Paused"
    },
    {
        "number": "456",
        "status": "Unavailable"
    }],
    "phone": "8558855858"
},
{
    "name": "Hilary",
    "queue": [{
        "number": "456",
        "status": "Unavailable"
    }],
    "phone": "5454573737"
},
{
    "name": "Edmond",
    "queue": [{
        "number": "665",
        "status": "Unavailable"
    }],
    "phone": "7454543737"
}];
$scope.a = [];
$scope.users = [];
for(i=0;i<data.length;i++){
    for(j=0;j<data[i].queue.length;j++){
        if(data[i].queue[j].number == 111 || data[i].queue[j].number == 456){
            $scope.a.push(data[i]);
        }
    }
}
$scope.users = $scope.a;
//console.log($scope.users);
   $scope.filter111 = function (user) {
            return (user.queue.find(({number}) => number === '111'));
        }
    $scope.filter456 = function (user) {
           return (user.queue.find(({number}) => number === '456'));
        }
});

app.filter('unique', function() {
   return function(collection, keyname) {
      var output = [],
          keys = [];
      angular.forEach(collection, function(item) {
          var key = item[keyname];
          if(keys.indexOf(key) === -1) {
              keys.push(key);
              output.push(item);
          }
      });
      return output;
   };
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.7.5/angular.min.js"></script>
<div ng-app="myApp">

<label class="switch">
  <input type="checkbox" ng-model="queue111">111
</label>
<label class="switch">
  <input type="checkbox" ng-model="queue456">456
</label>
<label class="switch">
  <input type="checkbox" ng-true-value='"Paused"' ng-false-value='' ng-model="paused">Paused
</label>
<div class="row" ng-controller="listdata">

  <div ng-repeat="user in users|filter: queue111? filter111: ''|unique:'name'|filter: queue456? filter456: ''|filter: paused track by $index">
    <p> {{user.name}} {{user.phone}}</p>
  </div>
</div>

</div>

I solved the issue by creating a custom function in the controller like this :

$scope.pausedc = function (user) {
          return (user.queue.find(({number,status}) => number === '111' && status === 'Paused' || number === '456' && status === 'Paused'));
      }

and html :

<label class="switch">
  <input type="checkbox"  ng-model="paused">Paused
</label>


<div class="row" ng-controller="listdata">

  <div ng-repeat="user in users| filter:paused? pausedc: '' track by $index">
    <p> {{user.name}} {{user.phone}}</p>
  </div>
</div>
