Skype for Business中未显示的卡和选项（Bot Framework）

Question

I recently add the skype for business channel to my bot, however Choices prompts and Hero Cards are not displayed in the message

   intents.matches(/^test/, [
  function (session) {
    const leaves = ['Holiday', 'Medical', 'Meeting', 'Seminar'];
    builder.Prompts.choice(session, 'Please select a leave request', leaves, { listStyle: builder.ListStyle.button });
  },
  function (session, args) {
    session.endDialog(`You are taking a ${args.response.entity} leave`);
  }
]);

Answer 1

The Skype for Business channel for Bot Framework is currently under Developer Preview.

Per the official documentation :

Cards and buttons : Skype for Business does not support cards and buttons in the Developer Preview. For the Developer Preview, cards and buttons are not shown to the user if they are sent by a bot. Cards and buttons fallback to text support will be added soon.
