Echo something to another terminal session?

Question

Is there any way to echo something to another terminal session, obtained from the who command? For example, root user echoes a message to a different user's terminal session, after getting their session from who. Is this possible?

Something like write someone pts/2 after mesg y? Or directly echo "Hi" 1> /dev/pts/1 — Pablo Bianchi, Nov 04 '22 at 01:54

That's very much possible with the write command

Example

$ write username </dev/ttyX>
