Nick name

Good afternoon, I would like to change the nickname on my Faceit account, due to my carelessness. When I did this by accident, this tick “546485” didn’t know that “Faceit Identification” was a nickname, and when he wanted to go back and play on Faceit, playing with such a nickname was extremely inconvenient, ridiculous, and so on. VERY big request to change it to the nickname “helix”. Have a good day.
p/s: I’ll prove my account in all ways
