How can I return back the first symbol register of my account name?

It seems accidently I changed the first symbol register of my account name (it became small).
How can I return it back (to big)?

Changing your username can only be done once and you are only allowed to change the case of the letters in your username.

lichess.org/account/username

You can change the capitalization here.

I had already changed once accidently and I want to return back.

Well you can't.
