unable to figure out subcommands

[Legend-Recalls]

i want to sendslash a command with a subcommand
it looks like this:-

my code:-
channel.sendSlash("289066747443675143",'top',"1");
or
channel.sendSlash("289066747443675143",'top','cmd',"1");
I reached out in documents previous discussions and issues but none of this helped me solved it so I apologise for any inconvenience

channel.sendSlash("botid",'top',"vipap");

[aiko-chan-ai]

hmm ?

cmd is just one of the many options, how do I specifically choose cmd only?
