How to change display name or username in CounterSocial app?

here's control social app and if you tap on your profile and tap on edit profile so you'll just be redirected to this page and then here you can change the display name you can change your bio so if you want to do that but I'm interested in changing my username so just to see how it works um and then you will be redirected to this web page and it keeps loading yeah so I guess here on this page you should be able to change your username so here if you just go there yeah so I guess it doesn't work for me but you can change your username from there
