how to politely correct someone?

I'm in a group chat and there's about 20-30 people in there.
This girl keeps spelling my name wrong but she's so nice and polite and sweet! I don't want to seem rude or seem like I'm embarrassing her in front of the other people so how do I kindly tell her lol that she's butchering my name with the spelling? 
I do not know all of these people personally. I don't know most of them actually. 
Any ideas lol
