Komenda na odbanowanie gracza

Witam, próbowałem na wiele sposobow lecz poleglem. Chcę aby komenda wpisana w konsoli bądź przez amina zmieniała wartość w pliku plugins/Ban/user/%player%.yml z ban true na false.

on load:
    if folder "plugins/Ban/" doesn't exists:
        create folder "plugins/Ban/"
    if folder "plugins/Ban/user." doesn't exists:
        create folder "plugins/Ban/user/"
    if file "plugins/Ban/config.yml" doesn't exists: 
        create file "plugins/Ban/config.yml"
        set "time" to "0" in yaml file "plugins/Ban/config.yml"
on join:
    if file "plugins/Ban/user/%player%.yml" doesn't exists:
        create file "plugins/Ban/user/%player%.yml"
        set "nick" to "%player%" in yaml file "plugins/Ban/user/%player%.yml"
        set "ban" to "true" in yaml file "plugins/Ban/user/%player%.yml"
        set "time" to "0" in yaml file "plugins/Ban/user/%player%.yml"

#Jak to przekształcić

command /unbanicja <offline player>:
    usage: /unbanicja <offline player>
    trigger:
        if arg false contains "%player%" from "plugins/Ban/user/":
            remove file "plugins/Ban/user/%player%.yml"
      
 

Jak coś skrypt jest w okrojonej wersji gdyż nie chciałbym go opubliczniać
