There is no possibility to answer on the direct message in MS Teams, that those messages are grouped in one thread like it is done it the channel, where this function exists. It would be great to have it in the direct messages as well, it helps to follow the discussion in a chat better. Otherwise when you post 3 different questions, the person with whom you are chatting starts to reply and it is not always possible to understand to which of these 3 questions the reply belongs. At least this issue exists on the Desktop version of MS Teams. We use the corporate version.
