Take over a conversation
Once you take over, it stays out of that thread until you hand it back.
Open any conversation and start typing and you have taken it over. There is nothing to switch on first.
From that point nothing is drafted or sent in that thread, even if replies are sending themselves everywhere else. Two voices answering one person is worse than a slow answer, so it stands down rather than helping.
Hand it back when you are done and drafting starts again from the next message.
Threads are kept for 12 months, so you can look back at what was said and by whom.
If this did not cover it, ask. A person reads it and answers the same working day.
