Antd 4 Checkbox doesn't have value after form submit

What I have

I have an Ant Design 4 form with a checkbox in it:

const Example = ({ initialValues, onSave }) => {  const [form] = Form.useForm();  useEffect(() => {    form.resetFields();  }, [initialValues.isAccepted]);  const onFinish = (values) => {    console.log(values);    onSave(values);  };  const getInitialValues = useCallback(() => ({    isAccepted: initialValues.isAccepted || false,  }));  return (<Form form={form} onFinish={onFinish} initialValues={getInitialValues()}><Form.Item name="isAccepted"><Checkbox>The company can use my data</Checkbox></Form.Item><Button type="primary" htmlType="submit">Save</Button></Form>  );};

Problem

The checkbox is always unchecked even if it is true inside initialValues. Also, when I submit the form the values variable always contains the value from initialValues, it doesn't registers that I changed (checked or unchecked) the checkbox.

Goal

I would like the initial value to be set properly from inititalValues and get the current value of the checkbox in onFinish.
