Should I go?

I’m in this group chat with some people that I share a class with but I’m not that close with them. Anyway, they want to do karaoke and since I’m in the chat I’m technically invited. But I don’t know if I should go or not since I’m not close friends with them and I’m an awkward bean. :/ (Also I can’t sing in front of people unless it’s in a medium-big group)
