Conversations (Chats) under Team Channels

There is definitely difference between conversation in Teams channel and chat. Conversation should usually happen in respect of the topic/post that is published in respective channel and should get replies dedicated to that post. Chat which is happening more realtime with all people in the Teams channel is very easy to be created...Just press Meet Now in the respective channel, create a new meeting, give a name to it, and even if you then end up the meeting, you can still leverage that group chat. This is the way how we do that for bigger audience chat which is built from some community. Otherwise I also create bigger chats by myself by adding participants of the chat manually and name it.
