[HELP] Using CUI_CHARACTER in ESX server

Hi! i’m using this script: https://forum.cfx.re/t/release-cleanui-cui-character/1914841
I want it to be the default menu when changing skin. This apply to creating the character, and changing clothes in shop. Developer says i need to stop esx_skin and skinchanger. The thing is this does not seems to work at all. Sometimes it will spawn me with random ped skin, and when i try to change character aspect, it just freeze me in my location, even blocking me from looking around.

Do anybody know how to implement this script in a already made ESX server?

Any help is appreciated. Thank You.
