And, actually, have other reasons why this option does not fit:
1. To use methods from TeamsInfo necessary initialized ITurnContext, which in my case should be defined by creation or continuation of the conversation between bot and user, that I cant to do because I have not UserID of Teams channel or ConversationID for this.
2. To use concrete TeamsInfo.getMembers method needs UserID that I wanna define.
