How to use list read/write in rpcd for luci

I added a new user kallel in /etc/passwd and /etc/shadow

and then I added the following section to /etc/config/rpcd

config login
        option username 'kallel'
        option password '$p$kallel'
        list read *
        list write system

then I access to luci WUI, I expexted to get access as a read only for all except the system pages, but I get readonly for all pages

What I am missing how I can configure it to access write for only system pages?
