Chatbox codes

Hi! I want to personalize my chatbox with these codes - https://help.forumotion.com/t139284-codes-to-personalize-your-chatbox#945354
But they don't seem to work. Do I have to create new javascript and paste code there or I'm doing it wrong?
Codes I tried to add but they don't work: Notification sound, Remove the lines "...joined the chat & ... has logged off the chat" and Automatic login.
My forum is - http://www.lshl.lv/forum

Hello @The Number 1

javascript codes are not added in the chatbox page. In order to use that codes you have to create an html page and add the chatbox in a frame, or instead, display the chatbox in the footer/header of your home page - or even in a widget

javascript codes are not available for chatbox yet (I hope)
