I follow a simple tutorial from Microsoft bot framework v3 guide to make a bot out of their Nodejs sdk. Bot is running, registered (but not published) it can be reached from 1 to 1 Skype conversation, where I have subscribed to my own bot, added to my contact.

But there isn't a + button to add new person to form a group. Neither I could add this bot into a group conversation.

I have enabled the "Group" capabilities in the bot , Skype setting. But it doesn't seems to be solving the problem? .
