The client/server machine that generates the TLS traffic doesn’t have to have Wireshark installed on it, so you don’t have to gum up a clients machine with stuff they won’t need, you can either have them dump the log to a network share or copy it off the machine and reunite it with the machine doing the packet capture later.
