I mean, I see chats is one continuous conversation and unless the conversation has been properly ended, it shouldn’t be necessary even if a night has passed.
Most people consider conversations ended if neither party adds anything for a space of time.
A reasonable space of time is definitely overnight.

Well there is your answer.
If you would view them as individual conversation, then putting a greeting at the beginning makes perfect sense.
