Hide kickoff button

Hello everyone
I am new here and very interested about jitsi
I am developing an app that uses jitsi sdk on iOS
Can you please tell me how can i hide or disable kickoff button ?
Thanks in advance

nano /usr/share/jitsi-meet/interface_config.js

look for

 /**
     * When enabled, the kick participant button will not be presented for users without a JWT
     */
    // HIDE_KICK_BUTTON_FOR_GUESTS: false,

remove // & set it up like this

HIDE_KICK_BUTTON_FOR_GUESTS: true

Thanks a lot for your reply

Is this in the iOS sdk !
Or i have to search in somewhere else ??
And how can i generate jwt for guests ?

sorry, this is the setting in jitsi-meet server side
