Need more sample such as Add, Edit or delete item

Hi, Choice.js is great library, but for some one like me (and many) if we dont see more samples, or related documentation its hard to use the library/component. Even for simple action that add, edit or delete Choice items "Dynamically" is really hard for me, for example :

<label for="choices-single-default">Default</label>
        <select
          class="form-control"
          data-trigger
          name="choices-single-default"
          id="choices-single-default"
          placeholder="This is a search placeholder"
        >
          <option value="">This is a placeholder</option>
          <option value="Choice 1">Choice 1</option>
          <option value="Choice 2">Choice 2</option>
          <option value="Choice 3">Choice 3</option>
        </select>

    <script>
        var genericExamples = new Choices(document.querySelector('[data-trigger]'), {
            placeholderValue: 'This is a placeholder set in the config',
            searchPlaceholderValue: 'This is a search placeholder',
            choices: [],
          });
    </script>

when im trying to delete an item, following "documentation" https://github.com/Choices-js/Choices#removeactiveitemsbyvaluevalue

genericExamples.removeActiveItemsByValue({choiceId: 2, groupId: -1, id: 8, label: "Choice 2", value: "Choice 2"});

i cant delete the item. i've tried

genericExamples.removeActiveItemsByValue(1);

//or trying following https://github.com/Choices-js/Choices/issues/634

choiceList.passedElement.triggerEvent('removeItem', ({id: 8, label: "Choice 2", value: "Choice 2"}))

but still none of the codes can delete the item.
