如下简单调用OCR，没有出现交互画面

<view>
    <ocr-navigator bind:onSuccess="success" certificateType="idCard" opposite="{{false}}">
      <button type="primary">身份证正面识别</button>
    </ocr-navigator>
    <ocr-navigator bind:onSuccess="success" certificateType="idCard" opposite="{{true}}">
      <button type="primary">身份证反面识别</button>
    </ocr-navigator>
  </view>
