Conversations involving multiple participants, allowing collaboration and information sharing in Teams
My only workaround this is >>"Copy the data dragging it from the bottom all the way up to the Name Icon(Headers) or ctrl+ A on the chat>>paste this in a notepad and only copy the chat what you need from this and paste the data anywhere with the timeline included>>works like a charm for me with the least time consumption.
This works for me in the desktop version of Teams (25094.310.3616.953).
Ctrl-A captures the name, timestamps, and reactions, but you have to delete any previous chat lines and there's also a summary line before the name/timestamp lines that you should delete as well. Still too time-consuming to edit to get what you need.
Copying data dragging downward or upward with the various methods did not work for me.
