I am a strong believer in "nohello" https://nohello.net/en/

If you use chat like it's a conversation then you'll have a bad time.

If you use it like it's business communication like short-form email it's better.

It's bizarre that the same people who will send an email that says "Hey, send me this information asap" will start a text chat with "hey how's it going"

People who say hello and then wait for a reply will wait a long, long time for a reply from me.
