Botbuilder SDK v4 creating 1:1 conversation from group

Question

I'm attempting to send a 1:1 / private message to a specific user who tagged the bot in channel in Microsoft Teams. Because there isn't a botbuilder-teams that is compatible with botbuilder v4, I figured I'd have to implement this functionality myself. I know with proactive messages, you can use adapter.continueConversation which works correctly, but adapter.createConversation does not. Here is the relevant piece of code within one of my dialogs:

let reference = TurnContext.getConversationReference(cx.activity);

await adapter.createConversation(reference, async (context) => {
    await context.sendActivity("Hello World!");
});

Answer 1

The first parameter for CreateConversation Method should be the channel ID, which is in your case "teams". You don't have to supply the existing conversation reference as you are creating a new one.
