Add/customize 404 error page for each domain

Hi, how can we modify or add a custom 404 error page and redirect visitor via .htaccess or other way? We are using LiteSpeed ent for 1 domain with cyberpanel.
I followed litespeedtech tutorial but their tutorial and our litespeed server consol are not same. Here is my litespeed consol screenshot at https://ip:7080

Please advice me. Thanks.
