Remarks
Message reactions correspond to the user adding a 'like' or 'sad' etc. (often an emoji) to a previously sent message on the conversation. Message reactions are supported by only a few channels. The activity that the message is in reaction to is identified by the activity's ReplyToId property. The value of this property is the activity ID of a previously sent activity. When the bot sends an activity, the channel assigns an ID to it, which is available in the Id of the result.
