Sending Friend Requests with a message

a lot of people never change the default setting that you can't message someone unless A) you are friends with them or B) you're in the same server. but if you try to send a friend request to them they may ignore it because they don't know why you're trying to friend them. I think there should be an option to send a message with a friend request (and really. this is a basic thing. PSN does it) for example what if you see a post online about someone looking for a rp. and they share their discord. there's no guarantee that they'll accept cause they may not realize why you're trying tomessage
