Bottender event helps you determine what kind of message is sent from user.

You can access context.event object within your handlers as the following example shows.

bot.onEvent(async (context) => {
  if (context.event.isText) {
    await context.sendText('I know you sent text message.');
  } else {
    await context.sendText('I know you did not send text message.');
  }
});
