You can use /aop command
You can use this command to add users to the list:
on *:text:*:#:{
if ($1-2 == !aop add) && ($3 != $null) {
aop $3 $chan
}
}
on *:join:#:{
if ($nick isaop $chan) { mode $chan +o $nick }
}
Place these commands in the remote (ALT+R)
Then just write in the chan: !aop add <nick>
