How can I modify HTML <video> tag attributes.

I'm using Captivate 2019 to make an interactive video product.

In order to make it playable on Android Apps (for example, Wechat，a famous IM application in China)，I should modify the HTML video tag like this，which provided by Tencent Browser Service(腾讯浏览服务-H5同层播放器接入规范 ).

  <video id="video" class="video" controls="controls" playsinline x5-video-player-type="h5">

Can anyone provide a solution?

Thank you!
