Clash of Clans Clan Name Change Option Missing

A long time ago, I created a clan in Clash of Clans called “wuncaki.” I would now like to change the name because I want to use the name “Eski şehir” so that other players can find my clan more easily.

I cannot find any option in the game to change the clan name, and I have no way to change it. I have not previously contacted in-game support about this issue.

I would like to request assistance with changing my clan name from “wuncaki” to “Eski şehir,” or, if this is not possible directly, I would appreciate clear instructions on the steps I need to follow to change the clan name.
