How can I filter on media type(s) using the mediapicker in angular? I see no such option in the documentation see my example below.

$scope.openMediaPicker = function (prop) {
    var mediaPickerOptions = {
        multiPicker: false,
        submit: function (model) {
            $scope.vm.tabledata.ListEditPropertyData.forEach(function (element, index) {
                if (element.FieldName == prop.FieldName) {
                    $scope.vm.tabledata.ListEditPropertyData[index].PropertyValue = model.selection[0].id;
                    $scope.vm.tabledata.ListEditPropertyData[index].ImageUrl = model.selection[0].image;
                }
            });

            editorService.close();
        },
        close: function () {
            editorService.close();
        }
    };

    if (prop.PropertyEditoryType == 'image') {
        mediaPickerOptions.onlyImages = true;
    }

    if (prop.PropertyEditorOptions != null && prop.PropertyEditorOptions.RootFolderId) {
        mediaPickerOptions.startNodeId = parseInt(prop.PropertyEditorOptions.RootFolderId);
    }
