# This class creates both outgoing messages from chatwoot and echo outgoing messages based on the flag `outgoing_echo`
# Assumptions
# 1. Incase of an outgoing message which is echo, source_id will NOT be nil,
# based on this we are showing "not sent from chatwoot" message in frontend
# Hence there is no need to set user_id in message for outgoing echo messages.
