Have you talked to that person before?
If you have, you might find some hook in the conversation you had and try to initiate your DMs.
If you haven't, you might wanna reprioritize certain things in life instead of having a crush on some dude online that you haven't even talked to.
The most natural way, if you interact with them in VRC, would be to take some good looking screenshots of them and then send it to them. People love getting their picture taken.
