Bounty Chat Message Tick Marks

Describe your feature request
Tick mark system on messages like whatsapp to know if the opposite part has read the message or not

What problem(s) would this feature solve?
I’ll tell you what problem i faced :
So i have sent chat in my current bounty chat thingy
the dude has been online on replit but hasn’t replied to my messages

He has before but now he wont idk why , he might be busy idk
but there is no way right now for me to know if he has read my messages or not

So if there is a tick mark thingy like whatsapp we can know if either party has read the message or not !


I think having some basic reactions like Github would also be nice.

Reference of what reactions Github has:
