I built a bot, enabled it for Skype with the option for Groups turned on.
When I chat 1-on-1 with the bot, it works fine, and it appears in my Contacts under "Bots"; but I can't add it to a group chat, it doesn't appear in the "Add People" list and even if I type /add my_bot_id Skype responds with my_bot_id can’t be added to this conversation due to his/her privacy settings.
What am I missing?
(edit: I'm using Skype for Mac, is that the problem...?)
From the bot chat tap the plus icon and add members. This will create a new group.
