How can I manipulate the scope value of an Angular dropdown menu using the console?

Is there a way to modify the value in a dropdown menu implemented in AngularJS using the Developer Tools Debugger?

I attempted the following code:

angular.element(
    getElementsByClassName('input-group ng-pristine ng-isolate-scope ng-empty ng-invalid ng-invalid-required ng-touched')[0]
).scope().model = 'Incorrect PO'"

Unfortunately, this approach did not yield any results. Typically, when modifying Angular elements, I add the 'ng-model' attribute at the end (in the previous example, the ng-model's attribute is named 'model').

<select name="creditReason" 
    class="input-group ng-pristine ng-isolate-scope ng-empty ng-invalid ng-invalid-required ng-touched"
    id="creditReason"
    required="required"
    ng-change="change ? change() : _.noop()" 
    ng-model="model" 
    ng-options="type.value as type.name for type in list"
    ng-disabled="(disableField || disabled)" 
    ng-required="lookupRequired" 
    ng-attr-id="{{lookupId}}" 
    model="confirmDialogCtrl.creditReasonCodeId" 
    lookup="creditReasons" 
    lookup-required="true" 
    lookup-name="creditReason" 
    lookup-id="creditReason"
    ng-attr-name="{{lookupName}}">
  <option selected="selected" value="?"></option>
  <option value="number:39001" label="Customer Request">Customer Request</option>
  <option value="number:39002" label="Discount Not Applied">Discount Not Applied</option>
  <option value="number:39003" label="Duplicate Billing">Duplicate Billing</option>
  <option value="number:39004" label="Incorrect Address">Incorrect Address</option>
  <option value="number:39005" label="Incorrect Billing Method">Incorrect Billing Method</option>
  <option value="number:39006" label="Incorrect Cost Center">Incorrect Cost Center</option>
  <option value="number:39007" label="Incorrect Customer/Season">Incorrect Customer/Season</option>
  <option value="number:39008" label="Incorrect PO">Incorrect PO</option>
  <option value="number:39009" label="Incorrect Rate">Incorrect Rate</option>
  <option value="number:39010" label="Incorrect Rental Period">Incorrect Rental Period</option>
  <option value="number:39011" label="Sales Tax">Sales Tax</option>
  <option value="number:39012" label="Other">Other</option>
</select>

Any suggestions on how to update the value of the dropdown menu would be greatly appreciated. I am particularly confused about the part that reads:

"ng-options" = "type.value as type.name for type in list"

EDIT: Can someone provide assistance with this issue? :(

Thank you!

To access the $scope using the method .scope(), you must utilize $apply to update the value of the model. According to the information found in the documentation

$apply() is specifically used to run an expression within AngularJS from outside of its framework.

By doing this, it becomes possible to modify the model directly from the console by executing the following code snippet

// Ensure the necessary classes are added for element accessibility.
// If there are no other elements with the same class name in the DOM, input-group should suffice.
const $scope = angular.element(document.getElementsByClassName("input-group")[0]).scope();
$scope.$apply(() => $scope.model = "number:39001")

Alternatively, if preferred, the operation can be condensed into a single line like so

angular.element(document.getElementsByClassName("input-group")[0]).scope().$apply(($scope) => $scope.model = "number:39001")
